(AP) Four people were stabbed in the parking lot at Sports Authority Stadium after the Denver Broncos' game Thursday night.
The Denver Police Department says on its Twitter page one person is in critical condition.
Police say that officers have "parties" in custody and are not currently looking for other suspects.
The Denver Post (http://bit.ly/18HGZb1) reports there were multiple eye-witnesses.
Police say that the incident was called in at 9:55 p.m.
Stadium Management Company says in a emailed statement that it is "aware of an incident that occurred in a parking lot adjacent to Sports Authority Field at Mile High" and it is working with authorities.
The Broncos lost 27-20 to the San Diego Chargers.
The stabbing Thursday is just one of several recent incidents involving football fans.
Earlier this month in Kansas City, Mo., a man died after an altercation in the Arrowhead Stadium parking lot during Kansas City's game against Denver.
In September in San Francisco, a teenage fan suffered a concussion and a broken arm and nose at Candlestick Park after police say he was attacked during the 49ers' game against Indianapolis.
