Kiev:Former WBC heavyweight champion Vitali Klitschko said on Thursday that his knee was nearly healed and that he was ready to win back his title. Klitschko had retired two years back after a series of injuries. His last fight was an eighth-round win over Danny Williams on December 11, 2004. The 36-year-old Ukrainian's back and knee problems forced a year's layoff afterward, then his retirement with a 35-2 record with 34 knockouts. Klitschko's younger brother Wladimir is the current IBF champion. Wladimir will defend his IBF heavyweight title against American boxer Ray Austin on March 10 in Mannheim, Germany. The elder Klitschko's comeback described his desire to be world champion alongside his brother as a 'major motive'. Klitschko failed in a recent bid to be elected mayor of Kiev, but has maintained a high public profile in the Ukrainian capital. He says his return to the ring doesn't mean he's setting aside politics.
