Challenger Tyson Fury received a hero's welcome, as he arrived at the MGM Grand to kick off fight week, before Sunday's (NZ time) huge WBC heavyweight title rematch with Deontay Wilder.
The Mancunian's reception was rapturous compared to champion Wilder's, with fans from both sides of the Atlantic cheering and applauding his entrance.
Fury, decked out in a typically colourful bespoke suit, bearing hundreds of motifs and featuring his own face, was in confident mood.
"I'm very happy so many people have turned out for this event," he said.
Grabbing the microphone, the Gypsy King roared: "Who's ready for a war?
"Let's go! I've done everything correctly in training camp, I've been over here for 10 weeks and I feel on fire.
"I'm ready for anything they chuck at me. I cannot wait for Saturday. This is the biggest fight of the last 50 years in the heavyweight division, with two men putting it on the line.
"The fans will be the winners, because we both have a lot to lose. It's going to be an entertaining fight.
"I'm still predicting a second-round knockout, 100 percent."
For his part, Wilder believes he will go on to make history.
"Greatness lies in me," he said. "It will be an amazing feeling, my 11th consecutive title defence.
"I'm tied now with my idol, Muhammad Ali, and once I've beaten Fury with a devastating knockout, I will go on even further to break the record and do more amazing things.
"My goal is for there to be one champion, one face, one name in the division.
"I'm in pursuit of that and I'm looking forward to fulfilling my goals and dreams."
