MASHANTUCKET, CT - Unbeaten rising middleweight Sergiy "The Technician" Derevyanchenko (9-0, 7 KOs) knocked down Sam "King" Soliman (44-14, 18 KOs) three times before stopping the former world champion in the second round of the main event of Premier Boxing Champions on ESPN and ESPN Deportes Thursday night from Foxwoods Resort Casino in Mashantucket, CT.

A 2008 Ukranian Olympian, Derevyanchenko was in control from the start, standing his ground and delivering smart shots as Soliman attempted to flummox him with movement and awkward angles.

Soliman got caught with a missile right hand from Derevyanchenko that landed right on the chin and sent the off-balance Australian to the canvas. Soliman didn't appear hurt however, as he continued to come forward to try to disrupt and frustrate the undefeated fighter.

Derevyanchenko continued to land effective shots and caught Soliman off-balance again in round two, this time with a left hook that put Soliman on the ground. Soliman again got to his feet but Derevyanchenko quickly stunned Soliman and put him into survival mode.

Soliman tried to tie up and avoid Derevyanchenko, but eventually the undefeated fighter training, who trains in Brooklyn, landed several right hands before a sweeping left hook sent Soliman to the ground hard and for the final time of the night. Referee Johnny Callas waved the fight off at 2:41 of the second round.

 "I looked into his eyes after I knocked him down the first time and I knew he would continue coming forward. I wasn't going to drop my guard. I didn't even feel that punch on my glove because it was so clean to the chin. But I felt the last knockdown," the unbeaten fight said.

"I warmed up more than once and that broke my rhythm. In the ring I had to get my rhythm. Soliman came out nervous and not very coordinated, but that's the way he usually fights. That's his style. I'm going to keep moving forward. I can't sit and wait. We will assess the situation and move from here."

Soliman hinted at the possibility of retirement.

"I'm doing well. I didn't get to warm up, just a couple of minutes, but that's no excuse. He did his job. That's never happened before to me. He's a good boxer who did what he had to do. I can't take anything away from him. After every fight, fighters have to decide what to do next. I have a lot outside of boxing that makes me happy, and it takes the sting out of tonight," Soliman said.
