ARTICLE 12.No Team A player may block an opponent until Team A is eligible to touch a free-kicked ball.
PENALTY —Live-ball foul. Five yards from the previous spot, or five yards from the spot where the subsequent dead ball belongs to Team B, or from the spot where the ball is placed after a touchback [S19].
Approved Ruling 6-1-3 II. Team A executes an on-side free kick at the A-35. The untouched kick is at the A-43 when A55 blocks B44 above the waist in the front at the A-46. A28 muffs the ball at the A-44, and after it rolls to the A-46, A88 blocks B22 at the A-42. A20 then recovers the ball at the A-44. RULING: The block by A55 is a foul and the touching by A28 is illegal, because Team A is not eligible to touch the ball since it has not gone 10 yards nor has it been touched by Team B. The block by A88 is legal because it occurs after the ball has gone 10 yards. Team A is in legal possession of the ball when A20 recovers it at the A-44. Team B has two options: Decline the penalty for the illegal block and have the ball at the A-44 via the illegal-touching privilege, or cancel the illegal-touching privilege by having Team A re-kick from the A-30 after the 5-yard penalty for the block by A55. Note that the dead-ball spot, the A-44, is not an enforcement spot because the ball does not belong to Team B when the down ends. (Rule 6-1-12)
