A Steelers fan made his way onto the practice field on Saturday with his own pads and helmet.  According to Antonio Brown, the fan was there to check him.

Talk about a set of balls.  Not only did he just walk onto the Steelers practice field, he called out the best receiver in the game.

Brown laughed the fan’s challenge off, but also told security to let the fan check him.

There was no chance this guy was going to walk on the practice field and shutdown AB.  But you have to respect the fan’s delusion or courage, whatever you want to call it.
