Another update from Sports Illustrated

BERLIN (AP) -- Former WBC heavyweight champion Vitali Klitschko hopes to return to the ring two years after injuries forced his retirement, according to a German report.

Klitschko, the older brother of IBF champion Wladimir Klitschko, plans to start his comeback attempt by working with a physiotherapist in Germany, the Westdeutsche Zeitung reported over the weekend.

"We already have a concept," Klitschko trainer Fritz Sdunek said. "First of all, though, it's important that Vitali's body stands up to the training."

Klitschko's last fight was an eighth-round stoppage of Danny Williams on Dec. 11, 2004. The 34-year-old's back and knee problems forced a year layoff afterward, then his retirement with a 35-2 record with 34 knockouts.

Smudek, who guided both brothers to WBO heavyweight titles, said the Ukrainians want to revive their old dream of owning the four major world heavyweight titles between them at the same time.

Klitschko failed in a recent bid to be elected mayor of Kiev, but remains active in Ukrainian politics and in business. Continuing the brothers' tradition, he still works the corner during the fights of Wladimir, who is three years younger.

Smudek said Klitschko will need a buildup fight before taking a title bout and would like the opponent to be Lennox Lewis, who is also retired.

The Klitschko brothers built their boxing careers in Germany, but Vitali has since moved to Los Angeles with his wife and three children.
