Though Magloire's foreman slammed against the bridge of his nose, Collison stayed in the 98-80 win. The team medical staff diagnosed a mild concussion later Saturday.
Collison, a fifth-year veteran from Kansas, is averaging 5.8 points and 5.1 rebounds as the primary backup to starting center Nenad Krstic.
Collison is traveling with the team on its four-game road trip. Brooks says he's not sure if Collison will play Wednesday at Minnesota.
