He tried to run on the court before the start of second half but was in obvious distress. Collison tried to test the ankle at the half but the team said he would not play in the second half.
Collison had scored 8 points and grabbed 2 rebounds in 15 minutes of action before leaving the game. A.J. Price has played more minutes in his absence.
