Cowboys' Morris Claiborne exits game vs. Saints with apparent knee injury

Dallas Cowboys cornerback Morris Claiborne exited Sunday's game against the New Orleans Saints with an apparent knee injury, needing help off the field and to the locker room.

Claiborne made headlines this past week when he went AWOL after being demoted from the starting lineup, but wound up effectively starting after all as the Cowboys opened the game in the nickel formation.

No word yet on the severity of the injury, but the Cowboys have tabbed Claiborne as questionable to return.
