The Jaguars hoped to split carries between Jennings and Jones-Drew on the heels of MJD's extended summer holdout, but those plans are fizzling away. Jones-Drew saw plenty of action in the loss to Minnesota with 19 carries for 77 yards and another 18 yards on three catches.
Mularkey also believes right tackle Cameron Bradfield could miss Sunday's game with an ankle injury, leaving the Jaguars scrambling along the offensive line. The newspaper reported Eben Britton could be shifted from left guard into Bradfield's spot unless they go with Guy Whimper.
Jones-Drew was going to find his way back into this starting lineup one way or another. The best news for any running back on this team is the improvement of quarterback Blaine Gabbert. For the first time in a while, this offense might be more than MJD staring down eight in the box.
UPDATE: Mularkey told reporters Wednesday that the MRI results for Jennings and Bradfield showed no significant damage. Neither player has been ruled out for the Texans meeting, so we'll keep an eye on this one.
