Three male victims were transported to the hospital -- one in critical condition and the other two in stable condition, police said. A fourth person believed to have been stabbed has not yet come forward and has not sought help, Denver police Sgt. Steve Warneke said.

The three victims were conscious and talking when they arrived at the hospital, Warneke said.

Three men are in custody and investigators are not looking for any other suspects, police said. Those suspects have not been identified.

The first call to police came in at 9:55 p.m. and it was reported as a large fight in Lot F near Dick Connor and Federal Boulevard, Warneke said.

There's no word yet on what caused the fight, police said.

The fight and ensuing stabbing occurred as fans were making their way to their cars after the Denver Broncos' 27-20 loss to the San Diego Chargers.
