Brutal KO with 20 seconds remaining in FDNY vs NYPD hockey game.

The closing moments of the FDNY vs NYPD game on Saturday night turned out to be barn burner, with multiple fights breaking out with less than a minute left on the game clock.

As we reported last night the fight between Thomas Esposito of the FDNY and Ryan Dermody of the NYPD would end in a devastating TKO courtesy of a huge bomb from Esposito, but the finish to the fight that would follow just 10 seconds later was even more brutal than the one that preceded it.

This time the two combatants would be John Perretta of the FDNY and James "Jimmy" Hall of the NYPD, and unfortunately for Hall it would become evident that he bit off more than could chew.

At no point did Hall mount any meaningful offense, instead acting like a punching bag for Perretta who showed his fellow first responder no mercy. Perretta would land a series of punishing lefts and rights, switching hands with ease, before eventually putting Hall down with a monsterous right hand and flexing for the crowd that roared with appreciation.
