Zac Brown Band headlined the World's Largest Music Festival - Summerfest - in Milwaukee, WI Sunday night.

The band drew quite the crowd into the Marcus Amphitheater, including former Wisconsin Badger football player JJ Watt.

When a "stage rusher" interrupted ZBB's set, JJ jumped in and put his football skills on display.



Nobody messes with Zac Brown Band
