I saw this in a game Saturday. Kickers were trying an onside kick. The ball hit the ground within the netural zone and took a high bounce. R came up about two yards inside the netural zone to attempt a catch. As the R player was attempting to catch, and before even touching the ball he was blocked out of the way by a K player.
I know it is not Fair-Catch-Int since the ball had already hit the ground. But after hitting the ground and before going the ten yards can K block R out of the way?
this happend in a NCAA game but if different would like NF rule Thanks
