tHE RATIONALE OF THS RULE:
less than 0:40 left ,but more than 0:25 left in period/half/game whatever.. B's coach -who is also a math teacher - could force A to run a play w/25 play clock by B player faking an injury. 40 sec. PC would allow A to run out the clock.
NOTE: I pushed this to be treated the same as 3-4-7 and only applicable to the last 2 of a half. I lost

.
RESULT: 11:59 remaining in 1st peroiod > B player injured > 40 PC.
