The Oklahoma City Thunder will be without Chet Holmgren for eight to 10 weeks after the forward underwent treatment on a small patellar tendon tear in his right knee, the team announced Friday.

Holmgren had missed the previous two games with what was described as right knee soreness before the tear was addressed. The team said the procedure — characterized as a biological treatment — was successful, but the recovery window pushes his return into the new year.

The timing compounds an already brutal week in Oklahoma City. Jalen Williams and Cason Wallace were both ruled out for extended stretches earlier in the week, meaning the Thunder have now lost three starters — all of them key pieces of the team's defensive identity — to significant injuries in the opening days of the season.

An 8-to-10-week timeline would put Holmgren's earliest return somewhere around the turn of the calendar year, leaving OKC to navigate a long stretch of its schedule with a badly thinned frontcourt and rotation.
