Mario Joly vs Matt Suderman

Right after the first whistle, Joly and Suderman drop the gloves and helmets, and square off. They size each other up and Suderman dives in first. Suderman throws the first punch that misses, as Joly grabs Suderman's jersey. Suderman tries again, but Joly's reach is better than his, as his punches are coming up short. Joly moves in a bit closer and Suderman catches him three times in the face. Joly shakes those off as Suderman's next two punches miss. Joly tries to tie up Suderman and connects with two uppercuts. Suderman switches hands and Joly puts him in a headlock. Suderman throws a wild overhand that connects to the back of Joly's head and sends him to the ice. As Joly gets hit, he lets go of Suderman's jersey and holds the back of his head. Suderman throws another punch that ends up missing but the momentum sends himself on top of Joly.

This was a tough call. Suderman definitely delivered a punch that sent Joly down but I believe it was a borderline TKO [if that even exists] simply because it may have been a momentum punch to the back of Joly's head that sent him down. But on the flip side; the fact that Joly covered up after the punch says otherwise. I'll call TKO, but I wouldnt dispute that last punch being a simple "knockdown" punch instead of "knockout" punch.
