World Boxing Association lightweight champion Vasyl Lomachenko (11-1) is set to return to the ring on Dec. 1 where he will challenge for another title at 135 pounds.

Lomachenko became the quickest three-weight world champion in boxing history when he moved up a division and defeated Jorge Linares in May. He was then expected to fight again in August in Los Angeles.

However, when he dislocated his shoulder in the fight against Linares only to pop it back into place, it resulted in a torn labrum which required arthroscopic surgery.

Lomachenko has since undergone surgery and is currently in his home country of Ukraine for rehabilitation and physical therapy. He recently traveled to Russia to watch his compatriot Oleksandr Usyk become undisputed cruiserweight world champion following his win over Murat Gassiev on July 21.

And according to his manager Egis Klimas, rehabilitation is going well and a next fight is already planned with Top Rank promoter Bob Arum.

"Rehab is going really good. Lomachenko came to support his friend and countryman Usyk in Moscow, so we spent three, four days together," Klimas said, as per ESPN. "He's working with his physical therapist. I think it's healing very good. I spoke with the doctor and the doctor said it was a good surgery. So we're looking to get him back on a checkup with the doctor."

"As far as the future, I just hung up [the phone] with [Top Rank promoter] Bob Arum and the plan is [Raymundo] Beltran is fighting [Jose] Pedraza on Aug. 25 and the winner [is] gonna be unifying titles with Lomachenko on Dec. 1."

The initial plan was for Lomachenko to face Beltran in August, but it was called off due to the pound-for-pound king's need for surgery.

Instead, Beltran will defend his World Boxing Organization lightweight title against Jose Pedraza on Aug. 25 at the Gila River Arena in Glendale, Arizona with Lomachenko waiting on the sidelines.

Should Lomachenko defeat the winner in December, he will hold two of the division's four titles which could set up a dream bout with World Boxing Council and International Boxing Federation lightweight champion Mikey Garcia (39-0) — a fight that has been proposed in the past at junior lightweight as well.

"We want that fight with Mikey Garcia. But Mikey Garcia is always walking out of that," Klimas added. "We want the fight with Mikey Garcia. Let me repeat it two times -- we want the fight. Lomachenko wants to fight Mikey Garcia. ... Always excuses, excuses."

"If he wants to come over, his management can talk to our management. We can find a solution. I'm sure the fight can be made together with ESPN and Showtime to do a pay-per-view fight [together]. If he wants to fight a welterweight, let him fight a welterweight in his next fight. He can keep his belts and unify next year."

Garcia most recently defeated Robert Easter Jr. via unanimous decision on Saturday to win his second belt.
