Baltimore Ravens safety Chuck Clark provided another defensive spark on the road.
Clark returned a fumble 65 yards for a touchdown, tying the Ravens' game at the Colts at 7 late in the first quarter.
This marked Baltimore's sixth defensive touchdown in its past 10 road games.
Ravens cornerback Marcus Peters ripped the ball away from Colts running back Jonathan Taylor, and Clark picked up the ball and sprinted down the sideline. After breaking free of a couple of tackles, Clark leapt over Indianapolis quarterback Philip Rivers at the Colts' 30-yard line before reaching the end zone.
