EDGE Analysis

Swift departed early in the second quarter and officially was ruled out at halftime of the contest, finishing Week 12 with a modest six touches for nine yards from scrimmage. Campbell said the Lions will take a "wait and see" approach with Swift's injury, which appears to be an aggravation of the shoulder issue that he picked up during a Week 10 tie at Pittsburgh. With Swift sidelined, Jamaal Williams took 15 carries for 65 yards and hauled in all five targets for 18 yards.
