James Prince had advised BoxingScene.com that he is now working in an advisory role with light heavyweight contender Ismayl "Black Russian" Sillakh (21-1, 17KOs), who on Saturday night will challenge undefeated WBO champion Sergey Kovalev (22-0-1, 20KOs) in an HBO televised fight from the Pepsi Coliseum in Quebec City, Canada.

Sillakh was won four in a row since last April's shocking upset to Denis Grachev, who came from behind to score an eight round TKO. During the match, Sillakh dropped Grachev and more or less dominated the entire fight - until he left himself open and got clipped several times on chin in the eight.

"I'm working with the Black Russian. I can't wait for Saturday, we're going down there to expose this boy," Prince told BoxingScene.com.

Prince works with Andre Ward, Bryant Jennings, Tavoris Cloud, Hank Lundy, Brad Solomon and several others.
