When a celebrity does this, there's usually a lawsuit coming: Future NASCAR Hall of Famer TONY STEWART took part in a sprint car race in Jackson, Minnesota the other night. And his engine blew one lap into it. So fans were disappointed.
Then he was signing autographs later, and some idiot in the crowd started yelling at him for QUITTING the race. There's cell phone footage, and you can see him trying to ignore the guy. But then they start flipping each other off . . . and it's ON.
Tony ran straight at the guy . . . threw a left hook . . . and LANDED it. It may have been a glancing blow. But he definitely hit the guy in the face. According to police, no charges have been filed . . . at least not yet. And it was "handled internally by race track officials."
