John Collins was ruled out for the second half of the Hawks-Cavs game as he is being evaluated for a concussion after taking an elbow to the side of the head in the second quarter.

The Hawks said his absence was for ‘precautionary reasons.’ Collins did return to the game after taking the hit and played more in the second quarter, but he didn’t come back for the second half, with Danilo Gallinari taking his place. On the play when Collins may have gotten injured, which involved a crowd of players under the basket, teammate Skylar Mays was actually called for a foul.

He is still being evaluated to determine whether or not he has a concussion. He is not necessarily ruled out for Wednesday’s game vs. the Celtics, but we’ll know more after he’s looked at by the Hawks’ training staff in the morning. Before exiting the game, Collins had 13 points and three rebounds in about 13 minutes.
