Cornerback Antoine Winfield is not practicing today as the Vikings continue preparation for Sunday's game with Arizona. Winfield suffered a neck injury in last week's loss at Kansas City and is still experiencing enough discomfort and stiffness for the team to hold him out of today's drills. Winfield's status for Sunday is looking more and more iffy. Head coach Leslie Frazier said Thursday afternoon that it might be a game-time decision on whether to play Winfield against the Cardinals or not. Frazier will speak with reporters at the conclusion of practice this afternoon.
