Colts coach Chuck Pagano: WR Austin Collie did suffer concussion. He felt good today. Listed day-to-day.
The Colts will likely be very, very careful with Collie. But the fact he's feeling good is perhaps a nice sign. But, that can change day-to-day. Collie should fall down your draft board. With his history, he's just too risky, especially if your draft is approaching over the next few days.
