At first, I thought Alley being on the boxer's back was just flavor text, until I realized there was a game mechanic advantage to the hold he has his opponent in, as it continuously allows Alley to attack from behind (and thus at a +2 bonus). So Alley establishes the hold on turn 1, then proceeds to punch at a bonus for the next three turns (2 attacks per turn if both combatants are fighting unarmed) because his opponent keeps failing a save vs. science to get Alley off his back.
Now, how the other boxer punches Alley out of the ring is another matter entirely. This "slam" effect I'll have to deal with someday, as it becomes quite prevalent in superhero stories later on. As of right now, there is no mechanic for ordinary fighters to knock each other over long distances -- though Supplement V: Big Bang has two powers for Superheroes modified to do this very thing.
