Jamaal Williams celebrated too much after scoring a touchdown on Sunday.

Williams pivoted to the right side of the field, ran 13 yards, and dove into the end zone to score a touchdown that helped increase the Lions’ 24-14 lead over the Vikings with 2:14 left in the third quarter in Minneapolis.

The Detroit running back then turned toward his teammates as he thrusted and gyrated his hips in celebration, a dance which garnered their approval, especially from offensive lineman Dan Skipper.

The referees, though, didn’t approve. Williams was flagged for unsportsmanlike conduct and drew a 15-yard penalty that put Detriot on their own 20 for the kickoff.

The penalty didn’t do much harm for the Lions: Minnesota’s Dalvin Cook fumbled the ball during the following possession and Detroit recovered. But Even with a 10-point lead through Williams’ touchdown, the Vikings rallied with two touchdowns in the fourth quarter to beat the Lions 28-24.

Sunday’s loss drops Detroit to 1-2.
