WBO junior lightweight champion Vasyl Lomachenko has thrown his name into the hat as a potential sparring partner replacement for Paulie Malignaggi.
However, the former WBA welterweight champion left the camp after he took issue at several leaked photos from their sessions that made it seem as if McGregor had knocked him down.
While the UFC lightweight champion has other sparring partners, he has now lost the one with the most boxing experience, with Malignaggi boasting a 36-8 record.
However, Lomachenko tweeted McGregor on Tuesday night, offering himself as a potential sparring partner: "Need another sparring partner to test your skills against?"
The Ukrainian (9-1 professional record) would be an upgrade on Malignaggi as not only is he yet to reach the prime of his career, but is considered by many as the pound-for-pound best boxer in the sport right now.
Lomachenko most recently defended his title against Miguel Marriaga on Saturday (5 August) in yet another dominating display as the 29-year-old was compared to boxing legend Muhammad Ali by Top Rank Promotions CEO Bob Arum.
Malignaggi responded to Lomachenko's offer, calling him a great mind to have in the camp but was unsure on whether he would be the best sparring partner due to his size as well as the fact that he is left-handed like McGregor: "I think Vasyl is a little guy, prob about 40lbs lighter currently but a great mind to have in Camp. However he is lefty though."
Regardless, this is not the first time that "Hi-Tech" has interacted with McGregor before.
Earlier this year in May, he asked him whether he should dive into the sport of mixed martial arts: "I used to win many wrestling, judo, and sambo tournaments as a kid. Should I try fighting in the @ufc ? What do you think @TheNotoriousMMA?"
As for sparring, Lomachenko has already sparred with another UFC fighter before, as he trained with former bantamweight champion TJ Dillashaw back in April.
