The Oklahoma City Thunder have suffered another major injury setback. Center Chet Holmgren will miss approximately eight to 10 weeks after receiving treatment for a small tear in his right patellar tendon, the team announced Friday, October 30.

The injury adds to Oklahoma City’s growing list of absences early in the 2026-27 NBA season. Holmgren’s absence is particularly significant because of his defensive presence, rebounding and ability to protect the rim.

According to the team’s announcement, Holmgren underwent a biological treatment on Friday to address the tendon injury. The procedure is intended to help him recover without requiring more invasive surgery. NBC Sports+1

Chet Holmgren Injury: What Happened?

Holmgren experienced mild discomfort in his right knee following Oklahoma City’s victory over the Phoenix Suns on October 25. The medical staff subsequently evaluated the issue and consulted with doctors before deciding on the treatment plan.

The Thunder confirmed that the injury involves a small patellar tendon tear. The expected recovery period is eight to 10 weeks, which could keep the 24-year-old center sidelined until the beginning of 2027.

The latest update also explains why Holmgren had missed Oklahoma City’s recent games. He was already dealing with a knee issue and was ruled out of the team’s upcoming road matchup against the Houston Rockets on Saturday, October 31. NBC Sports+1

Thunder Face Multiple Injury Problems

Holmgren is not the only Oklahoma City starter facing an extended absence. Jalen Williams suffered a dislocated left ankle and fractured fibula during the October 25 game against the Los Angeles Clippers.

Cason Wallace also sustained a torn labrum in his left shoulder during the same contest. The Thunder confirmed that Wallace would need further evaluation before the end of the 2026-27 regular season. NBC Sports

With three important players unavailable, Oklahoma City faces a difficult challenge in maintaining its rotation. The injuries affect both ends of the floor, particularly the team’s defensive structure and frontcourt depth.

Who Will Replace Chet Holmgren in the Thunder Lineup?

Isaiah Hartenstein is expected to take on greater responsibility in the center position during Holmgren’s absence. His rebounding, interior defense and experience will become increasingly important for the Thunder.

Kenrich Williams and Jaylin Williams could also receive additional opportunities. Rookie center Aday Mara is another option as Oklahoma City looks to manage its frontcourt rotation.

The Thunder have already made a roster move to address their injury problems, signing Ochai Agbaji on Friday to strengthen their wing depth. NBC Sports

When Will Chet Holmgren Return?

The announced recovery timeline is eight to 10 weeks. If the schedule remains unchanged, Holmgren could return during the first half of January 2027.

The biological treatment was selected to address the tendon problem without the need for more invasive surgery. A league source cited by NBC Sports identified platelet-rich plasma (PRP) therapy as a possible explanation for the procedure.

However, the Thunder have not announced a specific return date. His recovery and progress through rehabilitation will determine when he can safely return to basketball activities. NBC Sports
