Bills had 12 men on field for crucial OT play vs. Vikings play Why Orlovsky isn't putting all the blame for the Bills' loss on Josh Allen (1:57) Dan Orlovsky breaks down Josh Allen and the Bills' frustrating OT loss to the Vikings. (1:57) 12:05 PM ET Kevin SeifertESPN Staff Writer Close ESPN.com national NFL writer ESPN.com NFC North reporter, 2008-2013 Covered Vikings for Minneapolis Star Tribune, 1999-2008 The Buffalo Bills had 12 men on the field when they made a critical defensive play in overtime in their wild game Sunday against the Minnesota Vikings . The play occurred with 5 minutes, 17 seconds remaining in the overtime period, just after the Vikings had completed a 24-yard pass to receiver Justin Jefferson to set up a first-and-goal at the Bills' 2-yard line. On the next play, Vikings tailback Dalvin Cook was tackled for a 3-yard loss. Minnesota coach Kevin O'Connell said afterward that "I do believe there was 12 players on the field" on that play but said he wanted to confirm that via tape. An ESPN review of the game video clearly shows 12 defensive players. Had it been flagged, the Vikings would have had first down at the 1-yard line instead of second-and-goal at the 5.

"I know it's moving pretty fast out there sometimes," O'Connell said. Earlier, the NFL's on-site replay booth failed to initiate a review on what was ruled a completed 20-yard catch by Bills receiver Gabe Davis with 17 seconds remaining in regulation. Walt Anderson, NFL senior vice president of officiating, later told a pool reporter that the play should have been reviewed and that it would have been reversed to incomplete if it had been. That completion put the Bills in position to tie the game and send it into overtime.
