JJ Watt tackles stage-crasher at Milwaukee concert

Once his football career is over, Texans defensive end JJ Watt might have a future in security. That's something a concert-goer apparently learned the hard way Sunday.

According to the Houston Texans, Watt was at a Zac Brown concert in Milwaukee when a fan ran onstage. That's when Watt took matters into his own hands, tackling the stage-crasher and escorting him off stage.

The crowd went crazy as Watt nailed his target.

Whether the hit was staged or not is anyone's guess, but no doubt the stage-crasher is a bit sore today.
