Swift (shoulder) didn't practice Wednesday and could miss multiple games, though he wants to return in short order, Jeremy Fowler of ESPN.com reports.
Swift is reportedly dealing with an AC joint sprain, an injury that could prompt the winless Lions to take a cautious approach with one of their few core players until his shoulder heals. Though Swift hasn't been ruled out from playing in Sunday's game against the Vikings, he seems more likely than not to miss his first contest of the season. If that's the case, Jamaal Williams would be in store for a lead role Sunday, with rookie Jermar Jefferson and 27-year-old journeyman Godwin Igwebuike representing the depth options currently on the active roster.
