Sam Bradford expressed frustration after Thursday night's loss to the Dallas Cowboys after he appeared to be hit in the facemask on a two-point conversion attempt with just 25 seconds left in regulation.

The Cowboys defeated the Minnesota Vikings 17-15 in Minneapolis.

Bradford badly overthrew Kyle Rudolph on the potential game-tying play.

"He told me that I did not get hit in the face mask," Bradford said after the game of a conversation he had with officials.

"At the end of the day, that's a game-changing play and you've got to make those calls," defensive end Brian Robison said. "At the end of the game, Bradford gets hit in the face. That's an opportunity for us to score and tie the ballgame, but it doesn't get called."
