Nobody tries to crash the stage during a Zac Brown Band performance and gets away with it - NOBODY. Especially when you're in the presence of NFL star J.J. Watt.
The Houston Texans player -- who was watching from the side of the stage -- tackled one fan who tried to crash ZBB's set during Milwaukee's Summerfest over the weekend.
Watt posted a video on Twitter showing him tackling the stage crasher and getting cheers from the crowd as Zac Brown Band continued their performance. J.J. captioned the video, "Nobody messes with @zacbrownband." Indeed.
