Austin Collie's NFL career has taken yet another disappointing turn.
Multiple concussions have stalled the wide receiver's promising career. Thankfully, there was no such issue Sunday, but the knee injury is a devastating setback for a player who will be a free agent after the season.
Collie has the tools to be a successful receiver, but his durability issues surely will scare off plenty of teams. That includes the Colts.
UPDATE: Collie acknowledged his injury on Twitter later Monday.
