Foul on jump ball participant

[BillyMac]

Rule 4-19-3 An intentional foul is a personal or technical foul which neutralizes an opponent's obvious advantageous position. Contact away from the ball or when not making a legitimate attempt to play the ball or a player, specifically designed to stop or keep the clock from starting, shall be intentional. Intentional fouls may or may not be premeditated and are not based solely on the severity of the act. A foul also shall be ruled intentional if while playing the ball a player causes excessive contact with an opponent.

I'm leaning toward intentional, but I can be persuaded otherwise.
