UPDATE: Grimes has returned to the game, starting the second half.
With 1:34 left in the second quarter of Sunday’s game against the Atlanta Hawks, Quentin Grimes suffered a head injury after making a seven-foot floater. The referees sent him to the locker room due to concussion protocol.
Jared McCain was the substitute.
Prior to exiting, Grimes contributed 12 points, three rebounds and two assists in 15 minutes of action. McCain would be the biggest beneficiary if Grimes is out for an extended period of time.
