Bad weather in the Denver area forced a delay in the game between the Cowboys and Broncos at Sports Authority Field.
Play was delayed for nearly an hour as lightning was seen flashing in the sky near the stadium.
The game was stopped with 33 seconds left in the first quarter with the Cowboys trailing the Broncos 7-0.
A storm cell just to the southwest of the stadium is the culprit. Once it was deemed safe, players were allowed a 15-minute warmup period before play resumed.
