Holmgren, the No. 2 overall pick in this year’s NBA draft, suffered the injury Saturday while defending LeBron James on a fast break during a pro-am game in Seattle.
“Certainly, we are disappointed for Chet, especially given the excitement he had about getting on the floor with his teammates this season,” Thunder general manager Sam Presti said in a statement. “We know Chet has a long career ahead of him within our organization and the Oklahoma City community. One of the things that most impressed us during the process of selecting Chet was his determination and focus. We expect that same tenacity will carry him through this period of time as we work together and support him during his rehabilitation.”
The game was canceled in the second quarter because of the condition of the court. The unusually humid day in Seattle combined with a full crowd caused repeated wet spots and condensation.
The 7-foot-1, 195-pound Holmgren averaged 14.0 points and 8.4 rebounds in five games for the Thunder earlier this year at the Las Vegas Summer League.
