Swift logged 11 carries for 39 yards and hauled in eight of his team-high 11 targets for 65 yards and a TD in Sunday's 41-33 loss to the 49ers.
Meanwhile, Jamaal Williams -- who was announced as the Lions' starting RB for Sunday's game -- recorded nine carries for 54 yards and a TD and caught eight of his nine targets for 56 yards. It remains to be seen which back is tabbed as the starter next Monday against Green Bay, and if the team was inclined to ease Swift into the mix in Week 1 given that he's bouncing back from a groin injury. There was certainly a time-share scenario in play Sunday, but both players were involved enough to help those who rolled with them in fantasy lineups.
