After UFC 249, Khabib Nurmogomedov had said "Tony Ferguson's timeis finished', 'now, if he comes back, someone is gonna beat him again', 'after taking so much damage you can't be the same anymore- even if you are Tony Ferguson.' He was referring to the bad beating Tony received from Justin Gaethje in UFC 249.
Khabib's words gainded more popularity recently, after Tony lost to Beneil Dariush in UFC 262. Before that Tony had lost to Charles Oliviera in UFC 256. But Tony Ferguson has made it clear that he has no plans of retirement yet and that he would keep fighting.
