Colts wide receiver Austin Collie says he feels great despite two concussions during the 2010 season. "My body feels great, my head feels great," Collie said in a Sports Illustrated article that hits newsstands Wednesday. "I don't want to be the poster boy for concussions." Collie sustained his first concussion Nov. 7 at Philadelphia -- he was unconscious for 30 to 45 seconds and left the field on a stretcher -- and a second Dec. 19 against Jacksonville. He also was forced from a Nov. 21 game at New England by concussion-like symptoms.
