Barr won't play in the Week 17 season finale, either. The team decided to shut him down so that he could undergo what coach Mike Zimmer told reporters was a "very minor" procedure on his knee.
Barr, the No. 9 overall pick in the 2014 draft, originally suffered the injury in Week 11 and hasn't played since Week 14. Prior to the injury, Barr showed promise as a playmaker -- recording four sacks, forcing two fumbles and returning one for a game-winning touchdown -- and also was among the Vikings' leading tacklers with 70 in the first 12 games.
Meanwhile, tight end Kyle Rudolph returned to practice Friday to test his injured knee and ankle but is listed as doubtful to play on the final injury report of the week. Safety Robert Blanton (ankle), who also returned to practice, is listed as questionable.
