Ukrainian boxer Wladimir Klitschko announced Monday his scheduled world heavyweight title fight with Bulgarian Kubrat Pulev will be postponed because of an injury suffered in training.
"I am very disappointed the fight will not go ahead," Klitschko said in a statement, according to Reuters. "I am in top form and had a great training camp."
According to the report, Klitschko tore bicep muscles while training.
Klitschko's mandatory title defense was set to take place Sept. 6 in Hamburg. According to a German magazine, the fight will most likely be pushed back until late October at the earliest.
Pulev, 33, is undefeated in 20 career fights.
