Collison has arthroscopic knee surgery
The team says the procedure took place Tuesday. Collison will begin rehabilitating the knee immediately and should resume offseason training this summer.
Collison, a seven-year veteran, averaged 5.9 points and 5.1 rebounds this season in a reserve role for Oklahoma City. The Thunder lost to the Los Angeles Lakers in the first round of the NBA playoffs.
