Early career On 30 September 2017, Hrgović started his professional career with a first-round stoppage victory over Raphael Zumbano of Brazil. Hrgović signed a deal with
Sauerland Promotions following his debut. For his second professional fight, Hrgović was scheduled to fight the former Czech Heavyweight boxing champion Pavel Sour. The fight was evenly contested for the majority of the first round, until Hrgović landed a flurry 30 seconds before the end, knocking out Sour with a right hook. Hrgović was scheduled to fight the Tom Little, who was on a three-fight winning streak, on the undercard of the
World Boxing Super Series semi-final clash between
Oleksandr Usyk and
Mairis Briedis. Hrgović dominated throughout the fight, pressuring with a jab-right hand combination. He finally managed to knock Little down near the end of the fourth round, dropping his opponent with a right straight. Although Little managed to beat the ten-count, he had a cut over his left eye, and would quickly lose by technical knockout. Hrgović was expected to face Sean Turner, at the time the #46 ranked heavyweight according to
Boxrec, on the undercard of the
WBSS semifinal bout contested by
Callum Smith and
Nieky Holzken. Hrgović remained dominant in all eight rounds, with two of the three judges scoring the fight 80–72 in his favor, and the third judge scoring it 79–73. In his fifth professional fight, Hrgović was scheduled to fight the undefeated Mexican heavyweight Filiberto Tovar. It was the first time in Hrgović's career that he was scheduled to fight a ten-round bout. Hrgović once again dominated, stunning Tovar in first, second and third rounds, although he couldn't knock him down. Midway through the fourth round, Tovar's corner threw in the towel, awarding Hrgović a TKO victory. Following his five straight victories, Hrgović was shortlisted for
The Ring magazine Prospect of the Year award. Hrgović was scheduled to fight
Amir Mansour on September 8, 2018, for the
WBC International heavyweight title. It was both the first time Hrgović fought in his native
Zagreb, as well as the first time he was scheduled to fight in a twelve-round bout. In the first round, Hrgović utilized half-feints and jabs to pressure his opponent back, relying on his height and length to insulate him from Mansour's lunges. There was a brief break in action during the second round, after Mansour landed a blow to the back of Hrgović's head. After the break, the fight continued in the previous tempo, with Hrgović achieving a technical knockout win after knocking Mansour down twice in the third round. Hrgović was expected to make the first defense of his secondary title against Ytalo Perea on December 8, 2018, at the
Dražen Petrović Basketball Hall in
Zagreb, Croatia. It was scheduled to be broadcast exclusively by
RTL, domestically in Croatia. Perea was forced to withdraw two days prior to the bout due to
travel visa issues, and was replaced by former world title challenger
Kevin Johnson. Hrgović retained his title by unanimous decision, with all three judges awarding him all eight rounds of the fight. He dominated the bout from start to finish and came close to knocking Johnson down with an overhand right in the eight round, although he was unable to finish him. Hrgović was scheduled to make his second title defense against the 15–1 Gregory Corbin on May 25, 2019 at the MGM National Harbor in
Oxon Hill. The bout was broadcast domestically in Croatia by
RTL and internationally by
DAZN. It was Hrgović's United States debut, as well as his
DAZN debut. He won the fight by a first-round knockout, stopping Corbin after just 60 seconds, with his fourth strike of the bout. Hrgović had his first fight in
Mexico on August 24, 2019, against
Mario Heredia, at the Centro de Usos Multiples in
Hermosillo, Mexico. Heredia entered the fight off an upset with against
Samuel Peter, but was seen as an easy fight for Hrgović, as he had lost five of his past six bouts. Although he started slowly, Hrgović maintained a steady stream of jabs, right straights and hooks throughout the first round. Heredia attempted to adjust by landing a number of body shots in the second round, which failed to stop the forward movement of Hrgović. The fight ended in the third round, as Heredia was knocked out with a right-left hook combination. On 7 December 2019, on the undercard of
Ruiz Jr. vs. Joshua II, Hrgović, then ranked #9 by the
WBA and
IBF, and #11 by the WBC, had what is perhaps his most notable win to date, a third-round knockout against
Éric Molina. He dominated the fight from the first bell, dropping Molina twice; once in the first round and again in the second, before finally closing out with a third knockdown in the third round, from which Molina wasn't able to get up. Hrgović was expected to next face
Ondřej Pála in the co-main event of the
Dina Thorslund vs. Nina Radovanovic title fight, held on September 26, 2020, at the Struer Energi Park in
Struer, Denmark. Three days before the fight, Pála withdrew for an undisclosed reason, and was replaced on short notice by Alexandre Kartozia. Hrgović justified his role as the betting favorite, pressuring Kartozia throughout the fight, and knocking him out with a left-right combination at the 1:07 minute mark. Two months after his victory over Kartozia, Hrgović was scheduled to fight
Rydell Booker for the vacant
IBF International Heavyweight title o November 7, 2020, at the
Seminole Hard Rock Hotel & Casino, in
Hollywood, Florida, in his return to the United States. Hrgović entered the bout as a –10000 betting favorite, while most odds-makers had Booker at +1400. He justified his role as the betting favorite, stopping Booker with a flurry of punches in the fifth round. Following Hrgović's victory over Booker,
Michael Hunter called for a fight between the two, claiming he had asked for the fight numerous times before. Although the fight didn't materialize at the time,
IBF announced in February 2021 that the #5 ranked Hrgović and #4 ranked Hunter would fight to determine who would be the mandatory challenger for
Anthony Joshua’s heavyweight title. The organization gave both fighters until February 26, 2021, to accept the bout. Both fighters accepted the fight, although the time and place of it weren't immediately revealed, as they were to be determined after a bidding took place on April 6, 2021. The bidding was later postponed. The purse bid was eventually won by
Eddie Hearn’s Matchroom Boxing, who bid $606,666 for the fight, with a 60–40 split in favor of Hunter. Hunter withdrew from the bout following the purse bid. As the Hunter fight failed to pan out, Hrgović was instead scheduled to defend his IBF International Heavyweight Title against the undefeated Marko Radonjic on September 10, 2021, at
Wörthersee Stadion in
Klagenfurt, Austria. Hrgović thoroughly dominated his opponent, knocking him down seven times before Radonjić retired from the bout after the third round. Hrgović made his second IBF International heavyweight title defense against Scott Alexander at the
MGM Grand Las Vegas in
Las Vegas, United States on December 4, 2021. The bout was set for the undercard of a
DAZN card headlined by
Devin Haney and
Joseph Diaz. On November 30, five days before the fight, it was announced that Alexander had withdrawn from the fight and would be replaced by Emir Ahmatović. Hrgović won the fight by technical knockout, 30 seconds into the third round. Prior to the stoppage, he knocked Ahmetović down twice towards the end of the second round.
Rise up the ranks Hrgović vs. Zhang On January 3, 2022, the IBF sent an invitation to Hrgović and
Luis Ortiz to enter talks for a final title eliminator. Hrgović immediately accepted the offer, with his promoters stating: "Challenge accepted by Filip Hrgovic, [Three] days and counting for Luis Ortiz to accept". Ortiz refused, citing inability to compete due to injury. The IBF then invited the next highest ranked heavyweight contender,
Joseph Parker, to enter talks for a title eliminator bout. Parker refused to enter talks as well, due to recovering from injuries. On January 10, the same invitation was extended to
Tony Yoka. Yoka accepted the offer on January 13. The fight was supposed to be a rematch of their
2016 Summer Olympics semi-final bout, which Yoka narrowly won on points. The IBF later ruled Yoka ineligible to enter an agreement with any opponent other than
Martin Bakole, as the two had already signed contracts to face each other. On January 26, both
Andy Ruiz Jr. and
Murat Gassiev received invitations to enter into negotiations with Hrgović, which they refused five days later, citing lingering injuries as the reason for refusal. On February 7, it was revealed that the #13 ranked Chinese heavyweight
Zhilei Zhang had accepted the invitation to enter into negotiations with Hrgović. A purse bid was called by the organization on February 14, as the two camps failed to come to terms. Matchroom and Wasserman won the purse bid a joint bid of $650,000. Hrgović was entitled to a 60% split ($390,000), while Zhang received a 40% split of the purse ($260,000). The bout was expected to take place on May 7, 2022, on the
Canelo Álvarez vs. Dmitry Bivol undercard, as the co-feature to the main event. Hrgović withdrew from the bout on May 2, following the death of his father. The fight was rescheduled for the
Oleksandr Usyk vs. Anthony Joshua II undercard. It took place at the
King Abdullah Sports City in
Jeddah, Saudi Arabia on August 20, 2022, as part of a
DAZN pay-per-view. Despite a poor start, Hrgović was able to win the fight by unanimous decision. Judges Leszek Jankowiak and Robin Taylor scored the bout 115–112 in his favor, while judge Pawel Kardyni awarded Hrgović a 114–113 scorecard. Hrgović was knocked down with a check right hook in the back of the head, which is formally prohibited, in the last thirty seconds of the opening round and appeared to struggle with Zhang's power in the early parts of the fight. As it went on however, the Chinese boxer grew more exhausted and the volume of Hrgović was enough to earn him the latter rounds. The fight result was slightly controversial, and there was some disagreement among the media outlets as to the scoring. For example, BadLeftHook scored the fight 115–112 for Zhang, while Boxingscene had it 114–113 Hrgović.
Hrgović vs. McKean On November 13, 2022, the
IBF formally ordered their heavyweight champion
Oleksandr Usyk to enter into negotiations with Hrgović, who was at the time the mandatory challenger for the title.
Matchroom and Wasserman Boxing later confirmed that Hrgović opted to forgo the negotiation period and head straight to a purse bid. The IBF rescinded their order on January 9, 2023, as they recognized that the
WBA was next in the “rotation” for a mandatory title defense, with the stipulation that the winner would face Hrgović within 180 days. Ten days later, it was revealed that the IBF had ordered an interim title fight between Hrgović and the former
unified heavyweight champion
Andy Ruiz Jr. As the two camps couldn't come to an agreement, the IBF called for a purse bid to be held on February 28, which was eventually moved up to February 23. Ruiz declined to move forward with the interim championship bout hours before the purse bid was supposed to be held. As the expected bout against Ruiz fell through, Hrgović was instead booked to face the undefeated
Demsey McKean on August 12, 2023. The fight took place on the undercard of
Anthony Joshua vs. Robert Helenius, at
The O2 Arena in
London, England. Hrgović won the fight by a twelfth-round technical knockout. He was able to out-land McKean 173 to 116 in total punches and 148 to 90 in power punches. This victory earned Hrgović a reported €347,000 fight purse.
Hrgović vs. De Mori On October 6, 2023, the IBF confirmed they would strip the winner of the
Oleksandr Usyk and
Tyson Fury heavyweight championship unification bout, should the winner not immediately make a mandatory title defense against Hrgović. Hrgović faced
Mark de Mori in a stay-busy fight on the undercard of
Anthony Joshua vs. Otto Wallin, on December 23, 2023 at the
Kingdom Arena in
Riyadh, Saudi Arabia. It was his first fight as a free agent, as his promotional agreement with Wasserman Boxing expired on November 2. On the night of the fight, Hrgović was able to knock de Mori down in the very first minute of the opening round. The referee stopped the fight at the 1:44 minute mark of the first round, after Hrgović knocked his opponent down for the second time.
