Kicking?

[Texas Aggie]

Remember that "intentional" in this case means he's trying to or pretty much putting himself in a position to block the ball with his foot.

If a player is chasing a loose ball and inadvertantly kicks it, we have nothing. If a player is defending and jumps to block a pass while extending his legs outside of their natural vertical plane, and the ball hits it, then we have a violation. He may have thrown his arm out and not specifically intended to kick the ball, but he is responsible for his leg being in that position.
