Scores of fans gathered after the game Sunday night in central Denver for impromptu partying.

Longtime supporter Susan Tomlinson summed it up for many: "I've been a Broncos fan for 45 years. Way to go! What a run off for (Peyton) Manning for his last rodeo."

The crowd became unruly at times, but police for the most part watched the celebration from the sidewalk.

At one point, several dozen officers formed a united front near the 16th Street pedestrian mall to disperse a crowd trying to make its way down the street.

The Denver Post says police reported 12 arrests, mainly for criminal mischief.

The paper says police did use pepper spray on some people, and a window on a police cruiser was shattered in an area where people tossed trash cans in the street.
