Vitaly Klitschko stopped Manuel Charr of Germany in the fourth round to retain his WBC world heavyweight title Saturday night.
The 41-year-old Klitschko won by a technical knockout when the bout was stopped by the doctor with 56 seconds left in the round because of Charr's bleeding eyebrow.
It was Klitschko's ninth consecutive successful defense of the title since beating Samuel Peter in his comeback to the ring in 2008.
The Ukrainian has improved to 45-2 with 41 KOs.
The 27-year-old Charr, who was born in Beirut, suffered his first defeat and dropped to 21-1 with 11 KOs.
Klitschko dominated from the beginning and left little doubt about the final outcome.
Charr desperately protested the doctor's decision to stop the fight, but was finally calmed down by his assistants.
