Portland Trail Blazers wing Matisse Thybulle underwent surgery on Friday morning to repair a torn ulnar collateral ligament in his left thumb.
He will be reevaluated in four to six weeks, the team announced.
According to the Blazers, Thybulle suffered the thumb injury during Wednesday’s game in Utah.
The 28-year-old had an MRI on Thursday, which revealed the UCL tear.

It’s a tough blow for the guard/forward, who is now in his seventh NBA season. Thybulle is on an expiring $11.5M contract and will be an unrestricted free agent next summer unless he signs a veteran extension before the league year ends on June 30, 2026.
After playing at least 65 games in each of his first five seasons, Thybulle was limited to just 15 contests in 2024-25 due to knee and ankle injuries. The former first-round pick, who was selected 20th overall in 2019, is mostly known for his athleticism and top-tier defense, having been named to a pair of All-Defensive teams (in 2021 and 2022).
In four appearances this fall, Thybulle has averaged 5.0 points and 2.5 steals in just 12.3 minutes per game. It’s a very small sample size (49 minutes), but Portland has been much better when Thybulle is on the court (+21.0 net rating) than when he’s not playing (+1.8).
On a more positive note, oft-injured center Robert Williams will make his season debut on Friday versus Denver, interim head coach Tiago Splitter told reporters, including Sean Highkin of The Rose Garden Report. Williams was questionable to suit up earlier in the day.

Third-year wings Kris Murray and Rayan Rupert are candidates for more playing time while Thybulle recovers from thumb surgery.
