I remember there was some uproar about this but can't quite remember the specifics about where it changed or not. Think it was the Flanagan fight vs Zapeda that led to a bit of talk about the rule being changed

Not that ive heard of.

Not that I know of. The rule was applied perfectly correctly in the Flanagan-Zepeda fight, the only issue there was that people (not the officials) didn't know or understand the rule.

Accidental Fouls
1. If an accidental foul causes an injury severe enough for the referee to stop the bout immediately, the bout will result in a TECHNICAL DRAW if stopped before four (4) completed rounds. Four (4) rounds are complete when the bell rings signifying the end of the fourth round.

2. If an accidental foul causes an injury severe enough for the referee to stop the bout immediately after four (4) rounds have occurred, the bout will result in a TECHNICAL DECISION awarded to the boxer who is ahead on the score cards at the time the bout is stopped.

Partial or incomplete rounds will be scored. If no action has occurred, the round should be scored as an even round. This is at the discretion of the judges.
In the case of four (4) round contests the Foul Rule would come into effect at the bell ending round two.

In the case of six (6) round contests the Foul Rule would come into effect at the bell ending round three.

In the case of eight (8) round or above contests the Foul Rule would come into effect at the bell ending round four.

3. A fighter who is hit with an accidental low blow must continue after a reasonable amount of time but no more that five (5) minutes, or he/she will lose the bout by abandonment.
