The Jets are planning to use a committee of running backs to handle their workload on the ground this season, although that plan can only be implemented if there’s a stable of backs to use in support of Geno Smith or Michael Vick.

One of the players expected to be part of that stable suffered an injury in the preseason opener against the Colts on Thursday night. Chris Ivory injured his ribs late in the second quarter of the game and did not return. Ivory wasn’t necessarily going to play any more at that point in the game, but the injury would still have an impact if it limited Ivory’s availability in the coming days. Coach Rex Ryan wasn’t overly concerned about that possibility.
