At one point it smelled like an upset was brewing, but rising heavyweight power Arslanbek Makhmudov (14-0, 14 KOs) proved that his power was for real when he became the first man to drop Mariusz Wach (36-8, 19 KOs), who was stopped in the sixth round.

The Russian king of knockouts entered the fight looking sharp, trying to lull Wach to sleep from the very beginning. The Polish veteran, however, was prepared for it and stopped his attacks with the left straight.

After the first round had passed, Makhmudov was still advancing with a lot of pressure, but Wach was giving one of his better performances in years, with a strong straight left that was keeping Makhmudov at bay and hard rights that followed.

In the third round, Makhmudov hit Wach with a very strong overhand right. For a moment it seemed that this blow made an impression on Wach, but it only fired him up and urged him to fight fire with fire.

During the fourth round and fifth, Makhmudov's big punches were starting to gain steam and he was still looking for a knockout. Wach was still giving it a go and hanging in there with the big hitter.

Unfortunately, the end finally came in the sixth when Makhmudov unleashed a barrage of big shots, including a right hand to the jaw, that put Wach down. Wach got up, but he was in serious trouble and the referee waved off the fight.

In the co-feature, heavyweight Simon Kean (21-1, 20 KOs) hard to go through some fire, as he went to war with Shawndell Winters (13-7, 12 KOs), before stopping in the ninth round.

Both were down in the sixth round - before Kean dropped Winters twice in the ninth for the stoppage.
