What have the fighters said?
McGregor: "Sometimes we have to go to certain places in our life to realise what we need to do.
"I have turned over a new leaf. I feel the same young man but I feel re-energised and refreshed.
"I'm still a passionate young man, still reaching for the stars and aspiring to do things that have never been done before.
"There is no one who can touch me. I made this game what it is, so I am going to go in there and remind everyone."
John Kavanagh (McGregor's head coach on his new weight): "The final two weeks were about calorie deficit and sometimes things could get a bit tetchy.
"Instead of that there's dancing, music is playing, high-fiving and smiling."
Cowboy Cerrone: ""Moving forward my next six fights are all money fights, not just this one.
I'm stoked, happy to be here and to get the respect this old dinosaur deserves for being here.
"I've been in the sport a long time and I deserve the respect I get and it's cool to see Conor finally giving it to me."
