Holmgren Out Eight to Ten Weeks After Knee Treatment

Oklahoma City announced on Friday, October 30, that Chet Holmgren underwent a biological treatment for a small patellar tendon tear in his right knee.

He'll miss eight to ten weeks. The timeline puts his return between Christmas and the second week of January, and it costs the Thunder somewhere between 23 and 31 games. He isn't the only absence.

He's the third starter this roster has lost in the same stretch, and that's the story the building is living with. What leaves the lineup is specific: 12 points, 9.3 rebounds and 3.0 blocks a night across Holmgren's three appearances this season, in 30 minutes a game, per the Associated Press figures carried in the announcement coverage. Three blocks a night is the league's scarcest defensive commodity, and Oklahoma City built its scheme around his rim protection and floor spacing at the same time. There isn't a substitute for that combination on the roster. There's only a redistribution of it.

Isaiah Hartenstein takes the center minutes as the primary starter, and his early line reads 9.4 points and 9.6 rebounds in 23.8 minutes a night. Behind him stands Aday Mara, 21 years old and 7-foot-2, contributing 5.6 points, 4.2 rebounds and 1.4 blocks in 15.8 minutes. In the first start of the new arrangement, against Houston, coach Mark Daigneault opened with Shai Gilgeous-Alexander, Jared McCain, Ajay Mitchell, Kenrich Williams and Hartenstein. Kenrich Williams and Jaylin Williams stretch the remaining frontcourt minutes between them.

The other two chairs are emptier for longer. Jalen Williams had surgery on Wednesday, October 28, for a broken left fibula and damage tied to a dislocated, fractured ankle. Cason Wallace had surgery on Friday, October 30, to repair a torn labrum in his left shoulder. Both will be re-evaluated before the end of the regular season. A re-evaluation date isn't a return date, and the Thunder know the difference even if the fan base doesn't want to hear it. All three players started every game they played, and the injuries to Williams and Wallace trace to the same October 25 game where Holmgren's knee first bothered him.

The early returns without Holmgren split the difference: a 125-114 home win over Phoenix and losses at Dallas, 120-96, and at Houston, 119-98. The club has also paused a planned near-term signing of free agent Ochai Agbaji while it sorts out the frontcourt, per reporting on the announcement. That's the sound of a front office that won't spend a roster move until it knows which version of its team it's buying for.

Every NBA Cup group game on Oklahoma City's schedule falls inside the window: at Memphis on November 6, at the Clippers on November 13, home against New Orleans on November 20 and home against Minnesota on November 25. The Thunder built the league's deepest rotation for exactly this kind of month. The catch is that depth was supposed to be an advantage in April. In November, it's the starting five.
