Colts head coach Chuck Pagano said Monday that WR Austin Collie "did suffer a concussion" in Sunday's win at Pitttsburgh, according to the club's web site.
Said Pagano, per Colts.com: "He came in today, felt really good, was examined by the doctors and basically is going to be day-to-day. He felt really good coming out of the game this morning after being evaluated today.”
Collie, 26, caught 54 passes for 514 yards and a touchdown last season for Indianapolis, appearing in all 16 games. He suffered multiple concussions in 2010.
