"I want to thank God for the blessings he's blessed me with and my entire management team. It's been a year and it's time to get back in the ring. Since teaming with CrossFit, I've been doing so many different types of exercise and I feel great.
"I want to thank Kamegai for coming out here from Japan. I've seen film on him and he likes to brawl and bang it out and I am the same type of fighter so it will be a very exciting match for both me and the fans who will be watching. I can't wait for Saturday."
"My weight is no problem and I'm ready to go. I'm here to make a name for myself. I know that people have problems pronouncing my name ("kah may guy") so I want to make a great impact in this fight so they will learn to say it.
"Outside the ring I have the utmost respect for Guerrero. But inside, it's all business. This is will be a good fight, a hard fight and my opportunity to become a mainstay in the fight game.
"I plan on putting on a very exciting show on Saturday."
GARY RUSSELL JR.
"It's actually a little funny standing here getting ready to compete for a world title based on the fact that I was never a fighter that said I wanted to be a world champion until I was on the U.S. Olympic team.
"I was one of the favorites to medal (in the Olympics) and to not be able to compete was devastating. The only way that I could make it up to my fans and family was to become a world champion, plain and simple.
"In this situation I get the opportunity to kill two birds with one stone. My competitor fought in the Olympics and I can also become a world champion on this card. I can become a world champion on Saturday as well as beating an Olympian. It's the best of both worlds.''
"I want to thank everyone in my training camp and everyone who helped prepare me for the fight and my friends and family who are in Ukraine supporting me.
"I think it will be a very good fight on Saturday and I am looking forward to proving that I can win the featherweight title.''
"I want to thank my creator, without him I wouldn't be here. I would also like to thank Golden Boy, Oscar, everyone involved.
"This is a statement fight for me. I belong on top and I want to be on top. I have beaten some tough guys out there and on Saturday night I want to prove to you that I am the best. I plan on making a statement in the welterweight division and I look forward to the opportunity to show the world what I am capable of.''
JESUS SOTO KARASS
"Los Angeles is my second home. Coming off a loss against (interim WBA welterweight world champion) Keith Thurman, I want to come back and be impressive against Devon Alexander. He is fast, strong and has good foot speed, but I am ready to go.
"I am already at the contracted weight and I want to show the fans that I can come back and win. I have a mentality that I don't care and that I just want to win and show that I am capable of getting the victory.''
"I definitely feel that I am improving and prepared to fight my first 10-round fight. In camp, we picked up the cardio and conditioning, but we really haven't changed a whole lot.
"My last fight went eight rounds and it was the first time I'd gone the distance. But I always prepare to go the distance and for this fight I'm ready to go 10 hard rounds. But I'm really determined and always looking for the knockout.
"It's an honor fighting a fellow U.S. Olympian, but at the end there is only one winner and I want the referee to raise my hand. I look forward to exposing him and proving no doubt that I am better.''
"I'm looking forward to this fight and want to thank all those involved for making it happen. This is a big fight for me, for both of us. He may be undefeated but he hasn't faced anyone like me.
"We'll find out who is best on Saturday. But I'm confident and ready to go all-out to win.''
"I don't change for my opponents so I will keep my same style. I was able to get into the gym right after my last fight because it only lasted for 23 seconds.
"I was able to watch a few videos on my opponent but I don't know much about him. I won't give anything away on my style of fighting, but I will fight to the best of my abilities.
"I am ready for all six rounds for this fight if it goes that long, but at this time I won't know what the outcome will be. All I can do is prepare to the best of my ability.''
OSCAR DE LA HOYA, President of Golden Boy Promotions
"Our SHOWTIME EXTREME fights have always been highly competitive. It is one thing we at Golden Boy and SHOWTIME pride ourselves on. We want to consistently present the most competitive fights in the boxing business today.
"Chad Dawson is a great fighter who is back with a vengeance, looking to make a statement against a tough fighter in George Blades. For us, we look at this fight on SHOWTIME EXTREME as a great appetizer to the main course, which will also be very exciting.
"Guerrero is back, he's stronger, he's faster. The new team that he is working with at CrossFit will make a huge difference coming off the biggest fight of his career against Floyd Mayweather.
"That type of fight will elevate your game to a new level. We are looking forward to Saturday and witnessing a very much new and improved Robert Guerrero.
"All our matchups Saturday are exciting from top to bottom. We have an unbelievable history of staging fight-of-the-year candidates at StubHub. If you're a boxing fan and you love action-packed, competitive fights, the StubHub Center on Saturday will be a good place to be.''
