Winston (thumb) was spotted throwing passes at Friday's practice, Greg Auman of The Athletic reports.
Winston was limited to throwing tennis balls at Thursday's practice while working through a fractured right thumb, but the Buccaneers cleared him to use a football in the final session of Week 15. Winston's status for Sunday's game against the Lions is still uncertain, however, and it's possible a final call on his availability isn't made until game day. Ryan Griffin is the next man up on the depth chart at quarterback.
