The tallest player in college basketball history plans to take his long strides from Gainesville, Fla., to Orange County.

Olivier Rioux, who is 7-foot-9 yet seldom played at Florida, has committed to UC Irvine, he announced on Instagram. His move likely was prompted by the near certainty that he wouldn't crack the Gators' starting lineup next season, either.

Florida is expected to be ranked No. 1 entering the 2026-27 season after finishing 27-8 and ranked No. 9 in the final Associated Press poll behind three star players. Thomas Haugh and Alex Condon announced they would return and Rueben Chinyelu is expected to withdraw from the NBA draft and also return.

Rioux, who will be a redshirt sophomore, grew up in Quebec, Canada, and played at IMG Academy in Bradenton, Fla., before attending Florida as a preferred walk-on. He appeared in 11 games, scoring seven points, becoming the tallest player to score in a Division I game.

He will be fun to watch play regardless of whether he is dominant. Rioux dunks without jumping, a feat highlighted by his first college field goal against Saint Francis in December 2025 and a memorable March Madness moment in 2026 with an offensive rebound and put-back dunk.

He didn't play more than a few minutes at a time because Florida coach Todd Golden said he lacked the stamina to do so.

Mamadou Ndiaye, who is 7-6, played at Irvine from 2014 to 2016, likely confident he would be the tallest ever to suit up for the Anteaters. Ndiaye twice was named Big West defensive player of the year and helped Irvine to a Big West Conference title and NCAA tournament berth. He played five years in the NBA, including for the Clippers in 2004-05.

Rioux is one of only three college basketball players in history taller than the decorated former Irvine center, according to ESPN. The Anteaters can only hope Rioux makes a similar impact.

Last season Irvine won the Big West regular-season title but lost to Hawaii in the conference tournament. The Anteaters went 32-7 in 2024-25. Guard Jurian Dixon starred on both teams but transferred to Virginia this offseason.

According to the Florida media guide, Rioux is the Guinness World Record holder for tallest teenager. He stood 6-1 at age eight, 6-11 by sixth grade and became a certified 7-footer the next summer. Rioux played on Canada's national team at various age levels.

The center redshirted in 2024-25 when Gators won the national title in 2025 and appeared in 11 games last season. In late March, he announced that he would enter the portal in search of more playing time. On Thursday, he made a decision.

"Next stop: Irvine, California," he wrote on social media.
