American Football Rules IFAF Approved Ruling 6-3-1:III

III. A1 interferes with B1’s opportunity to catch a kick when a scrimmage kick fails to cross the neutral zone. RULING: Interference with the opportunity to catch a kick does not apply (Rule 6-4-1), and all players are eligible to touch, recover and advance the ball. Therefore, any player legally may push an opponent in an actual attempt to get at the ball (Rule 9-3-3-c-3); but no player may hold an opponent to prevent his reaching the ball, or in an attempt to permit a teammate to reach it (Rules 9-1-5 Exception 3 and 9-3-6 Exception 3).
