At least three people — and possibly four — were stabbed in the parking lot of Sports Authority Field at Mile High amid a large fight following the Broncos’ loss to the Chargers on Thursday night.

One person was in critical condition and two people were stable, but the injuries were not believed to be life-threatening, Denver police said. Police believe a fourth victim who has not come forward was also stabbed. The three victims are men.

Three people were arrested, and Denver police said they didn’t believe any other suspects were at-large.

The incident occurred around 9:55 p.m. in the stadium’s Lot F near the intersection of Dick Connor Avenue and Federal Boulevard.

“This was a very chaotic scene,” Denver Police spokesperson Steve Warneke said. “There’s lots of witnesses. We’re going to be interviewing witnesses throughout the night … we’re not sure what led up to this.

“I don’t know if this is game-related or what caused this.”

Three victims, all men, remained in area hospitals.

“They are conscious and talking,” Warneke said.

No descriptions of the suspects or victims were released, but one man was seen in the back of a police cruiser and was eventually taken away. It was not clear whether the person was a witness or suspect. Warneke said police had no indication so far that the incident was gang-related.

Officials for the stadium released a statement late Thursday:

“Stadium Management Company is aware of an incident that occurred in a parking lot adjacent to Sports Authority Field at Mile High. We are currently working with authorities to gather more information.”

The Broncos declined comment Thursday night.

The game — won by the Chargers 27-20 — finished about 9:25 p.m. And the apparent fights broke out on the west side of the stadium in a parking lot.

It was the second Broncos game this season that was followed by a violent incident. A man died after an altercation in Kansas City on Dec. 1 after the Broncos beat the Chiefs.
