Kolb sustained the concussion during last week's season-opening loss to the Green Bay Packers, clearing the way for Vick to play against the Lions, his first NFL start since 2006. Vick was with the Atlanta Falcons at that time, then missed the 2007 and 2008 seasons while imprisoned on federal dogfighting charges.
Vick was 21-of-34 passing for 284 yards and two touchdowns against the Lions. He also ran for 37 yards on seven carries.
Linebacker Stewart Bradley also passed the concussion tests and can practice this week. Reid said Bradley would start next week, too.
