There are currently 4 contenders for Khabi'b's belt. Tony deserves the next shot if/when he's ready. Assuming Khabib sticks by his word and waits until November/December, there'a a chance Tony will be able to return (not sure of his timeline).
If this is the case, the division is in trouble, assuming Conor doesn't return, since there are 3 legitimate contenders - Poirier, Eddie, and Lee. Assuming two of them face off before the end of the year, how do you determine who is the odd man out? Poirier vs. Eddie seems like the obvious fight to make given how their last fight ended, but where does that leave Kevin Lee?
The LW division is one of the two most loaded divisions in the UFC. We have to wait to see how everything plays out. If Conor comes back and is actually willing to fight Khabib for the title, they can easily make Eddie-Poirier and Tony-Lee happen. However, the odds seem to be highly unlikely that will occur.
