I'd throw Bader or Janitor in there, as they're scheduled to faceoff in late January and I'm pretty sure Janitor is always good to go. Te Huna, Jimmo and Vinny are also possibilities.
Diabate didn't take too much damage against Griggs, he's a possibility and I betcha Maldonado would be down if he could get medically cleared in time. Vera and him are teammates, so that's out.
I don't know what Mousasi's contract is like(SF or Showtime), but if they're closing shop in Janurary anyways, he'd be a great co-main addition.
Regardless, whoever takes the fight will have to cancel Christmas and have a short-camp against a top LHW....be very interested to see who they book.
