Swift (groin) was a limited practice participant Thursday.
Swift was sidelined for the entire preseason slate due to a groin injury, and there was some question whether he'd be able to handle a full workload Week 1 against the 49ers with veteran back Jamaal Williams on hand. Swift nearly doubled Williams' snap count on offense (63 versus 32) while the pair put up similar stat lines (Swift had 19 touches for 104 total yards and one TD; Williams had 17-110-1, respectively). Now, both backs are limited in practice, with Williams dealing with a chest injury. The Lions don't play until Monday night in Green Bay, so both Swift and Williams have a bit more time than normal to prepare for game day.
