Dallas Cowboys quarterback Dak Prescott appeared to be a bit sour after losing to the San Francisco 49ers 23-17 in the NFC wild-card round on Sunday evening.

Prescott’s season came to an end after he decided to run the ball on a quarterback draw with 14 seconds left and no timeouts. He ran the play successfully but failed to get another play off to stop the clock. A debate brewed over whether the Cowboys’ play-calling at the end the of the game was inept or whether the NFL officials made a mistake by taking too long to officially spot the ball.

Cowboys fans who were at AT&T Stadium watching the game were clearly upset over another disappointing way to end a hopeful season.

NFL Network reporter Jane Slater tweeted a video appearing to show fans throwing debris on the field while the officials and Cowboys players were entering the tunnel.
