The clip shows the punch landed flush… and the guy appeared to be cold on his feet – toppling over and falling to the ground.
Other fans in the area rushed to the puncher to hold it back… and the cops finally arrived at the scene.
A spokesperson for the Denver Police Department, however, said TMZ Sports no arrests were made… explaining: “The person who threw the first punch was contacted by the police. However, the beaten person did not want to press charges. “
The game continued despite the action in the stands… with the Rockies winning 3-2 in the extra innings.
