Wiesblatt began his ice hockey career playing for the Calgary Bisons U15 AAA in the
Alberta Major Bantam Hockey League before being drafted into the
Western Hockey League (WHL). Prior to being drafted 25th overall, Wiesblatt recorded 38 goals and 35 assists in 32 games during the 2016–17 season. In spite of being drafted, he remained in the
Alberta Midget Hockey League with the Calgary Bisons U18 team but was selected for Team Alberta at the 2017 WHL Cup. He made his WHL debut during the
2017–18 season, during which he recorded his first career WHL goal. Wiesblatt officially joined the Raiders roster for the
2018–19 season where he recorded 39 points and helped lead the team to the
Ed Chynoweth Cup. As a result, he shared the team's Rookie of the Year award with
Kaiden Guhle. This caught the attention of
San Jose Sharks' general manager and director of scouting, who referred to Wiesblatt as a center rather than a winger. Wiesblatt entered his first year of draft eligibility ranking 19th overall North American skaters per the
NHL Central Scouting Bureau's Midterm Rankings. Although the season was shortened due to the
COVID-19 pandemic in North America, he placed second on the team in scoring with 70 points in 64 games. As a result, he was drafted in the first round, 31st overall, by the San Jose Sharks in the
2020 NHL entry draft. He signed his contract on October 16, 2020. On March 18, 2024, Wiesblatt was reassigned by the Sharks from the San Jose Barracuda to the Milwaukee Admirals. He played out the remainder of the season with the Admirals, posting 6 points through 16 regular season games and adding 9 points in 15 playoff contests. He was traded by the Sharks to the
Nashville Predators in exchange for
Egor Afanasyev on June 23, 2024. On January 3, 2025, Wiesblatt made his NHL debut with the Nashville Predators. ==Personal life==
