EDGE Analysis

Chachere suffered the injury on the last play of the game, in an unlucky turn of events. Prior to going down, Chachere recorded two tackles and one pass defensed. He is fighting to make the Colts' roster to serve in a depth role in the secondary and also potentially contribute on special teams.
