Damian Knyba TKO8 Marcin Siwy... Heavyweight Damian Knyba (16-0, 10 KOs) scored an eighth-round stoppage over Marcin Siwy (25-1-1, 12 KOs) in an all-Polish showdown held in Newark, New Jersey. Knyba, who stands six-foot-seven, enjoyed a six-inch height advantage. He used an extended lead hand to keep Siwy at range while the shorter man lunged forward headfirst, looking to work on the inside. The early rounds were filled with clinches, but Knyba found his rhythm in the fifth and sixth, digging to the body and landing around the guard. By the seventh and eighth, he easily landed the right on a bloodied Siwy, who offered less and less in return. Siwy made it back to his corner after the eighth but was ruled unable to continue.
