Gigashvilli was a latecomer to the sport, telling
Midi Olympique that he had not seen a rugby match until he was 20 years old. Returning from the army, he was persuaded by a friend to join a training session- six months later, he signed for
Spartak GM Moscow in Russia. In France, Gigashvili helped
SO Chambéry win the Jean Prat Trophy at the conclusion of 2016–17
Fédérale 1 season. His former coach,
Cyril Villain, described Gigashvili as "versatile", "hard-working", and possessing "very good scrummaging" skills. He signed with
Grenoble in 2017. Following the
2019 Rugby World Cup, Gigashvili signed with
Toulon, a move he described as being influenced by previous successful spells at the club for compatriots including
Mamuka Gorgodze,
Levan Chilachava and
Konstantin Mikautadze. He made his debut in a 20-13 win against
Bayonne in the
2019-20 European Rugby Challenge Cup in November 2019. He made a strong impression in his first season, bringing stability to the Toulon scrum and winning praise as a powerful carrier, including for his first try for
les rouges et noir in a 41-19 win over
Clermont. Gigashvili suffered a hamstring injury representing
Georgia against
Fiji in the
Autumn Nations Cup, having started in all their previous games in the competition against
England,
Wales and
Ireland. In February 2021, he renewed his contract with RCT until 2024. At the end of the 2021/22 season, he represented
the Barbarians for the first time, starting in a 52-21 win over
England at
Twickenham Stadium and did the same as Georgia defeated
Italy 28-19 in
Batumi, his nation's first win over a
Six Nations side. Gigashvili began the
2022-23 Top 14 season in good try scoring form, crossing the line in victories against
Clermont,
Pau and
Stade Français. He was rated as the regular season's best tighthead prop by
Midi Olympique, describing him as a 'nightmare' for opponents in the scrum. Gigashvili scored a try and was man-of-the-match as Toulon defeated
Benetton Rugby 23-0 to reach the final of the
2022-23 EPCR Challenge Cup, before starting in the final as part of a 43-19 win over
Glasgow Warriors at the
Aviva Stadium. ==References==
