Porter sustained a hamstring injury in Saturday's preseason loss to the Bengals, Brad Biggs of the Chicago Tribune reports.

EDGE Analysis

Porter's path to making the Bears' 53-man roster got a little bit easier after the team released Tim Jennings following the game, but Alan Ball appears in better position than Porter to claim the starting cornerback role opposite Kyle Fuller. If the injury -- which kept Porter out of practice Monday -- proves to be significant, his chances of cracking the roster could take a serious hit.
