Post fight interview, Khan says that he will still be fighting.
He will keep fighting because he still can, and that's money every fight. (win or loss)
However, with his recent showings, his stock went down so I don't know, maybe he can go back fighting no names again to gain some confidence before he can fight another top level boxers.
That's probably he needs do first, this guy is calling Manny IIRC and I'm sure he will regret if they ever fight, Manny maybe older
than Crawford but they have the same power.
He is also not getting younger, so just few more fights before he retires.
It's not about the age I guess, Manny is still fighting at his age now and choosing younger opponents.
