Anthony Joshua v Joseph Parker
Meanwhile, back stage...The stare of a champion...
Alexander Povetkin v David Price
David Price heads to the ring as some wild western music is played around the Principality Stadium. He really is in the last chance saloon tonight.
This time it's Welsh.....

Creed was ace and we can all agree on that and the latest in the Rocky saga will feature the raucous crowd in the Principality Stadium.
They have just been filmed doing the requisite level of booing and cheering and the film producers are seemingly happy with what they've got... so on with the boxing.

The lights dim, the crowd fills the few seats that were left empty and suddenly, things feel more intense.
The crowd here are being asked to cheer for boxing names while being filmed by the makers of Hollywood film ‘Creed 2’.
Anthony Joshua’s name gets a cheer, Deontay Wilder’s gets a boo as does Dillian Whyte’s.
Whyte, ringside, laughed his head off.
Alexander Povetkin v David Price
Tyson Fury, the Brit who beat Wladimir Klitschko before Anthony Joshua did, is likely to play a big role in the heavyweight scene in the next few years as he looks to return to the ring after an absence of more than two years.
But at the moment he is just in a spectator role, although he is closely following tonight's events and has produced a video on Instagram, external supporting David Price in his bid to beat Alexander Povetkin.
"I just want to wish David Price all the best for his fight with Povetkin," said Manchester-based Fury. "We had our differences in the past David but I have grown to admire and respect you as a fighter and as a person. Povetkin is a former world champion but he is half the size of you and very small compared to us.
"All you need to do is land one punch, one detonating right hand and you have catapulted yourself back into the heavyweight division and you are going to get a fight with whovever you want after you knock out Povetkin.
"Believe in yourself, yes, you can do it. You are David Price the knockout king in the heavyweight division and I have faith in you. Come on David, do it for the North West."
Alexander Povetkin v David Price
Former undisputed world heavyweight champion Lennox Lewis says Alexander Povetkin will be the toughest opponent David Price has ever faced.
Alexander Povetkin v David Price
Although David Price has lost four times in his career, some of those losses have proved controversial.
Two of his defeats came in back-to-back fights against American Tony Thompson, with another against Germany's Erkan Tepper. Both Thompson and Tepper failed drugs tests in the aftermath.
Price has been vocal about the issue, yet steps into the ring with Alexander Povetkin, who has twice failed drug tests himself.
"If I was in a position to say 'no, he's failed a drugs test', I would. But the position I'm in, I need this opportunity way more than getting on a moral high horse about drugs in boxing," Price told BBC Sport in Cardiff.
"Drugs in boxing has impacted on me directly a couple of times. I have played my part in getting rules changed. Now I'm at the point where I have lost care for it. The subject has defeated me. There's no point me wasting my time thinking and talking about it."
Alexander Povetkin v David Price
Heavyweight David Price is one of the few men to have knocked Anthony Joshua down, doing so in a training session in 2010.
However, the Liverpudlian's career has not hit the heights many expected as the 2008 Olympic bronze medallist has lost four of his past 11 fights, although he has a chance to catapult himself into the big time tonight with a win over former WBA champion Alexander Povetkin.
"I am desperate," Price told BBC Sport. "I am up against it. But in every sport, there are upsets weekly. It's a massive opportunity for me to turn around my boxing career. I have to get the win and change my life in the process. I'm not supposed to win this fight. It can wipe out any negativity in my career."
"Early on in my career I was expected to do this and that but I haven't. You become an easy target for critics. You know people are dismissing you and not taking you seriously anymore. That's difficult. There are times where I haven't felt like a professional fighter anymore, I've felt like a normal man."
Ryan Burnett beats Yonfrez Parejo on points
WBA bantamweight champion Ryan Burnett speaking to Sky Sports: "I was getting into the fight, but in the third round round I think I broke my hand - at the beginning of the round.
"I had to rely on my boxing skills to get me through the fight."
Asked who he hopes to face next: "I'm up for anything now, I'm fortunate to be where I am. I'm up for any challenge."
Ryan Burnett v Yonfrez Parejo
All credit to Ryan Burnett, he made that look so convincing. And then tells everyone he thinks he may have broken his hand during the fight. Heart of a champion. A sensational performance. What a talent. Fought 19, won 19.

BBC Sport boxing reporter at the Principality Stadium
Dillian Whyte, Carl Froch, Sugar Ray Leonard and Frank Bruno are just some of the boxing stars ringside.
When Bruno came to sit down, Whyte - who won well last week - spotted him and raced over to say hello.
All these years on big Frank is still a star in the eyes of both fans and boxers alike.

Ryan Burnett v Yonfrez Parejo
Never in doubt. Ryan Burnett retains his title. Two judges give him every round at 120-108. The other has a rather puzzling scorecard of 116-112, only a four-round gap.
Anthony Joshua v Joseph Parker
Anthony Joshua's opponent Joseph Parker speaking to Sky Sports: "I'm feeling great. The whole team is relaxed, we're just playing some music.
"I'm 100% confident of what I can do in the ring. That's why we wanted this fight. It's my destiny, my time.
"I'm ready to make my mark on the world."
England defender Harry Maguire says Joshua in four.

Alexander Povetkin v David Price
David Price speaking to Sky Sports before his fight with Alexander Povetkin, which is the next contest up: "The time is now. I’m desperate to win but I’m calm, relaxed and prepared.
"Now is the time and I'm going to back in this dressing room celebrating. It [beating Povetkin] is going to put me right in the big fights – that's the reason I’m in the sport.
"He [Povetkin] is good, he’s tough and I am up against it on paper - but I believe it is going to be my night."
Ryan Burnett v Yonfrez Parejo
Last round. Ryan Burnett may have taken every round. Only a moment of complete carelessness will cost him his world title.
The legend returns to the Principality Stadium... when was he here last?
Michael Pearlman
BBC Sport Wales at the Principality Stadium
Sugar Ray Leonard is providing the presence of a genuine boxing legend at the Principality Stadium tonight.
However, this is not the first time Leonard has been at Wales' national stadium.
Can anyone remember the first time?
Probably only if you were fans of the short-lived boxing reality show, the Contender.
Sugar Ray Leonard served as executive producer of that show and was in attendance when one of the contenders, Peter Manfredo Jr, took on Calzaghe in 2007. Calzaghe won in three.
Speaking of Lennox...
Britain's Lennox Lewis, the last man to be an undisputed world heavyweight champion, expects to see one man holding all the belts in the heavyweight division in the not too-distant future.
Remember, Joshua holds the IBF, WBA and IBO titles, Joseph Parker the WBO title and American Deontay Wilder the WBC belt in the alphabet-world of boxing.

ChrismanSpurs: The best has to be Lennox Lewis. He fought *everyone*. It was name after name after name and he pretty much owned them all. Even avenged his 2 defeats. Legend.
NA Burton: Joe Calzaghe. Truly world class and hugely underrated; Barry McGuigan for uniting people and Tony Sibson for getting me into boxing in the first place!
Orfordjazz: Henry Cooper. No contest!
