Nowitzki was participating in an event before Game 3 of the NBA Finals
NBA champion Dirk Nowitzki learned the hard way that giving a fan an opportunity to dunk over you can be a risky proposition.
The seven-footer appeared at a promotional event outside the Dallas Mavericks' home arena before Game 3 of the NBA Finals, and a fan at the event was eager to show off his dunking prowess.
Nowitzki stood under the basket and held the ball behind his head as the fan got a running start.

But the fan's dunk attempt was unsuccessful.
"Damn, Chris," an announcer said in reaction to the attempt.

The fan did not even manage to get the ball from Nowitzki's hands. He instead landed on the former NBA star's back, almost knocking him down in the process.

The collar on Nowitzki's blue shirt popped up as a result of the failed dunk. Aside from that, the Mavs legend appeared OK.
