HAMBURG, Germany — Wladimir Klitschko's management says he will defend his multiple heavyweight titles against Alexander Povetkin in a highly anticipated showdown on Oct. 5 in Moscow.

Klitschko holds the IBF and IBO belts and is also the WBO and WBA "super champion." Povetkin is WBA's "regular champion."

Klitschko's older brother Vitali is the WBC champion. The Ukraine-born brothers have dominated the heavy division for a decade.

Like Wladimir Klitschko, Russia's Povetkin is a former Olympic champion and has a 26-0 record, with 18 KOs.

Klitschko is 60-3. His last fight was a sixth-round TKO over Francesco Pianeta in May.

The Klitschkos rarely fight outside Germany, their base. Povetkin is the mandatory challenger but it took long to finalize the bout.
