[SC Official]

If an official posts a fist, he can look for another fist or hand. For example, the Big 12 All-Access video showed a play in the Baylor-OU game where James Breeding, the L, raised his fist to call a charge by Quincy Acy of Baylor, but saw that Joe DeRosa, the T, had a different foul on Oklahoma 21, and wisely held off, because the foul by 21 caused Acy to charge.

Officials can come together if both raise a fist, but once the block and charge are both signalled, in NCAAM or NFHS rules, the calls cannot be withdrawn. This, therefore, is a situation where an ounce of prevention (using proper signals to stop the clock and scanning the floor before making a preliminary signal) is worth a pound of cure (enforcing both fouls).

You might be the first person on this forum to talk to veteran posters like they've never officiated anything above wreck league ball.
