A fan decided to run on the field at the end of the Raiders-Broncos game on Sunday.  Security guards gave chase and eventually took him down, but not before one of them suffered a broken ankle.

The fan used a pretty good cutback and stiff arm combo to shake the tackle of the Broncos security guard.  The move sent the security guard flying.

When the security guard landed, he broke his ankle and had to be carted off the field so the final seconds of the season for the Broncos could be played.
