Christian Koloko is suffering from a blood clot issue that has put his young NBA career in jeopardy, according to a report from The Athletic’s Shams Charania on Thursday.

Koloko has reportedly been referred to the NBA’s Fitness-to-Play panel, which prevents him from playing for or practicing with an NBA team until he is medically cleared. Koloko was waived by the Toronto Raptors on Wednesday to help facilitate a trade with the Indiana Pacers, and Charania reported that he has no shortage of suitors.

But the health of the 23-year-old is first priority at the moment.

Koloko has not played this season with what the Raptors have called a respiratory issue. At a press conference on Thursday, Raptors president Masai Ujiri spoke on Koloko’s situation.

“His medical status is now in the hands of the NBA,” Ujiri said. “But that’s a very tough one for us because that’s somebody we really believed in, someone that I know has incredible talent, and we saw as a future on this team, but we’ve exhausted all our options there.”

The 7-footer from Arizona was drafted with the 33rd overall pick (second round) of the 2022 NBA Draft. He was the Most Improved and the Defensive Player of the Year in the Pac-12 during the 2021-22 season after averaging 12.6 points and 7.3 rebounds a game for the Pac-12 champion Wildcats.

As a rookie last season, he appeared in 58 games while making 19 starts. Koloko averaged 3.1 points, 2.9 rebounds, and one block in 13.8 minutes a game.
