I agree with BillyMac and the officiating director...I don't see this as anything more than a common foul. I do not think he kicked at the player on the floor. I think he was flailing around trying to get the ball free and the foot to the face was the unfortunate result. A foul, absolutely. Flagrant, I don't think so.
Heck, some might even make the argument that it should have been a block on the player that was on the floor since the player on the floor didn't have LGP (NCAA-M interpretation).
