They could if they really wanted to start of their Russia entrance with a BANG.
I would really like to see Khabib vs Conor in Russia in Luzhniki Stadium. That would be Epic. At the moment there are 3 equally big promotions on Russian market, but with an event like they could blow everyone else away.
1 conor never coming back and 2 if he does he not agreeing to fight in khabib back yard.
