I haven't seen any mention if he is recovering from an injury. In the game where he ran for a first down somewhere in the middle of the game he got down early and he seemed to limp slightly when he was headed back to the huddle. He also seemed to be tentative in the 4th quarter when a few runs could have extended drives. It could be that they didn't want him to run with us up by 3 scores, but it did feel like there was some caution in his taking off.
