Colts' Anthony Walker Jr.: Leaves game with hamstring injury

Walker suffered a hamstring injury and didn't return to Sunday overtime win over the 49ers, Kevin Bowen of 1070 The Fan Indianapolis reports.

Walker hadn't practiced until this week after sustaining a hamstring injury in the season opener, and it appears he may have aggravated the injury Sunday. The rookie fifth-round was ruled out shortly after exiting in the second half.
