O'Malley isn't convinced Chimaev will return to the octagon

Sean O'Malley, UFC flyweight champion, has spoken out about the future career of Hamzat Chimaev.

"Dana White said that Hamzat is very, very sick, even 'gravely ill'. I'm wondering if his immune system is so bad, if he's so strong mentally that he's training when he should be resting. I don't know, maybe he has some kind of disease. Who knows if we'll see Hamzat in the octagon again. I think Chimaev has already withdrawn from fights six times," said O'Malley on his YouTube channel.

Recall, Chimaev was forced to withdraw from the fight against Robert Whittaker due to health problems.
