Reitz started Sunday in place of injured guard Hugh Thornton (knee). Reitz was hurt on a running play in the third quarter and then taken to the locker room for further evaluation and X-rays. As he lay on the ground, Colts quarterback Andrew Luck came over to console Reitz, who is in his fourth season from Western Michigan.
Reitz is the second Colts lineman to go down. Earlier, rookie center Jonotthan Harrison left with a neck injury and didn't return.
Browns cornerback K'Waun Williams sustained a hamstring injury in the first half.
