The Minnesota Vikings have already ruled quarterback Sam Bradford out for their Week 4 game against the Detroit Lions due to a knee injury.
Per Chad Graff of the Pioneer Press, Vikings head coach Mike Zimmer noted Bradford is "feeling better, he's just not ready to play" when he announced the quarterback wouldn't play Sunday.
Bradford hasn't played since Week 1 against the New Orleans Saints when he threw for 346 yards and three touchdowns in Minnesota's 29-19 victory.
