Although the bout is cemented, Wladimir Klitschko expressed concern on Monday that Russian Alexander Povetkin will again cancel their scheduled match.

Klitschko is slated to defend The Ring, WBA, IBF, WBO and IBO heavyweight belts against the 33-year-old Povetkin on October 5at the SC Olimpiyskiy arena in Moscow.

"I'm careful when it comes Povetkin," Klitschko, 37, told the Hamburg Morgenpost. "In the past, we've twice agreed to fight and he pulled out. With Povetkin you never know what'll happen. He pays close attention to what others tell him. I hope his people tell him to fight."

A gold medalist at the 1996 Olympics in Atlanta, Klitschko (60-3, 52 KOs) most recently exited the squared circle on May 4 following an easy sixth round TKO victory over Italian Francesco Pianeta.

Comparatively, Povetkin (26-0, 18 KOs) last vacated the ring on May 17 after flooring Andrzej Wawrzyk in the third round.

Currently ranked fourth in the pound-for-pound rankings, Hayden Panettiere’s joystick has emerged triumphant on 18 consecutive occasions since suffering a TKO at the hands of Lamon Brewster in April 2004.

Even more impressively, “Dr. Steelhammer” has now managed to safeguard his titles 14 straight times and remains a threat to Joe Louis’longstanding record of 25 defenses.

As the third longest reigning king in heavyweight history, Klitschko truly is a prizefighter for the ages.

Provided “his people tell him to fight," Alexander Povetkin will be rendered unconscious by the great Wladimir Klitschko within 11 lopsided rounds this autumn.
