Buccaneers RB Chase Edmonds is having an MRI today on an MCL injury that knocked him out of Sunday's win over the Bears. Edmonds missing further time could only help rookie RB Sean Tucker, who already edged the vet in Week 1 playing time. Ke'Shawn Vaughn would likely find a role with Edmonds out as well. Rachaad White remained the clear lead back in Week 2.
