Floyd Mayweather said he was willing to fight Manny Pacquiao again after the Filipino boxer repairs his torn shoulder muscle, an ESPN report said on Tuesday.

Mayweather won last weekend's richest boxing world title showdown before Pacquiao disclosed that a shoulder injury hampered his performance.

"I will fight him in a year after his surgery," Mayweather said, according to ESPN.

Mayweather's willingness contradicted with his remarks after match that he would retire after one more fight in September.

Pacquiao's camp have complained that the Nevada State Athletic Commission barred the fighter from receiving treatment for the injury using an anti-inflammatory injection approved by the United States Anti-Doping Agency.
