INDIANAPOLIS -- Colts starting cornerback Vontae Davis left Sunday's game against the Washington Redskins in the third quarter with a concussion.
Davis suffered the concussion when he tried to tackle Redskins running back Roy Helu.
Davis bounced off Helu and remained on the ground for several minutes before walking off the field on his own power.
Josh Gordy replaced Gordon and was beaten by Redskins receiver DeSean Jackson for a 42-yard touchdown reception several plays later.
