Jets RB Joe McKnight left in the 2nd half of Sunday’s game against the Redskins with an elbow injury and did not return. After the game, he was unable to extend the elbow. He’ll undergo an MRI on Monday. RB LaDainian Tomlinson, who reinjured his knee on Sunday but returned to the game, will step back in as New York’s clear #2 back if McKnight misses time.
