He can take or not take fights and I don't think they can refuse him switching weight classes. They only don't book people (at lower weights) when they've shown they can't make weight repeatedly, IIRC.I dont think Walker hás any say on who to fight. Being a veteran, his contract is probably more expensive than what he's worth. They got the hype that they could get about of him and até This point the better return he can bring tô the UFC is his looney tunes KOs. They"ll Ferguson him.
Btw, Walker probably will get ko'd by fainting on the Weight cut
I guess Walker decided against that HW move.
Why not Rountree rematch?
