Tim Tszyu undergoes surgery on both hands, eyes Charlo-Castano II winner

Unbeaten junior middleweight contender Tim Tszyu underwent arthroscopic surgery on both his hands recently, but it should have no impact on his schedule.

The 27-year-old is the WBO's mandatory challenger and wants the winner of the upcoming rematch between Jermell Charlo and Brian Castano, which takes place May 14 at Dignity Health Sports Park in Carson, California.

Tszyu's manager told reporters the operation was to repair his knuckles.

"Tim has been fighting with sore hands for the last few fights, so given the extended time frame we have awaiting the Castano versus Charlo rematch it was prudent to have the problem addressed," Tszyu's manager Glen Jennings said via The Courier Mail.

"We had the corrective surgery to ensure Tim's hands are ready for the biggest fight of his life. Our team doctor, Dr Bill Anseline, consulted with renowned hand surgeon Dr Damien Ryan who was extremely happy with the surgical outcome and assured Tim that he would be ready for his world title fight with two good hands ready to go."

Tszyu (21-0, 15 KOs) made his U.S. debut in March, when he recovered from a first-round knockdown to dominate Olympian Terrell Gausha over 12 rounds.
