D.J. Harvey is a 6-6 high school sensation at traditional Washington powerhouse DeMatha Catholic, and as Keith Jackson used to say, "He's ooonnnllly a soph-o-more!"

Harvey, who already has big-time college programs interested, nearly knocked himself out in a recent game when he jumped so high trying to block a shot that his head crashed into the backboard.

The play occurred during DeMatha's 51-47 win against St. John's on Dec. 3. It is just starting to make the rounds on the Internet as photographer Brian Kapur realized he had captured the moment of impact:

Harvey is ranked 17th nationally among players in the Class of 2017, according to Rivals.com.

Looks like this is a classic case of a player being so good that he can only stop himself.
