Collie is working his way back from a knee injury that cost him all but a game last season with the Indianapolis Colts. He also has suffered three serious concussions in his career and told USA Today Sports in June that he would sign a waiver if required in order to play.
"I'll sign a waiver, all right?" he told USA Today. "They're not going to have to worry about me suing. I'll hold myself to be accountable."
"I just need that closure. When I feel like I accomplish everything I want to accomplish, I'll have no problem walking away from the game. But I have more to give."
Collie has 173 career receptions in 42 regular-season games (16 starts), totaling 1,845 yards and 16 touchdowns.
Collie is BYU's all-time leader in receiving yards (3.255) and touchdowns (30).
