In a search for heavyweight titleholder Wladimir Klitschko's next mandatory challenger, the IBF plans to sanction a four-man tournament with the winner earning a title shot. If the IBF has its way, the field will include Calvin Brock (31-1, 23 KOs) and former titlist Chris Byrd (40-3-1, 21 KOs), both of whom were knocked out by Klitschko last year, along with American up-and-comer Eddie Chambers (29-0, 16 KOs) and Alexander Povetkin (13-0, 9 KOs), the 2004 Russian Olympic gold medalist. If the proposed fights come off -- which is certainly not set in stone -- Byrd would face Povetkin with Brock facing Chambers. The winners will fight with that winner earning a fight with Klitschko. Chambers and Povetkin are all for it. "This is the opportunity I've been looking for," Chambers said. "It's sort of like the NFL playoffs. Win a couple of rounds and get to the Super Bowl against Wladimir Klitschko. That's just what I intend to do -- not only get to the Super Bowl, but win it too, a world heavyweight title. But my focus and attention right now is preparing for my semifinal opponent, Calvin Brock." Said Kalle Sauerland, Povetkin's co-manager: "This is the chance Alexander has been waiting for. We have no doubt he will prevail in this interesting tournament."
