Both Abner Mares and Leo Santa Cruz are causing a buzz after stepping up in weight and knocking out their respective opponents.

Andre Ward spoke to RingTV.com about rehabbing his shoulder injury, fighting in September, doing HBO commentary for the Chad Dawson-Adonis Stevenson fight, a potential showdown with Julio Cesar Chavez Jr., fighting in the UK, and making a documentary of his time away from the ring. 

Lamont Peterson's younger brother, Anthony, will compete in a lightweight bout on Saturday's undcard to Lamont's 141-pound main event against Lucas Matthysse.

RING and WBA super middleweight champion Andre Ward said he plans to return to the ring in September, and mentioned former WBC middleweight titleholder Julio Cesar Chavez Jr. as a potential opponent.  

Former WBC middleweight titleholder Julio Cesar Chavez Jr. will decide between Martin Murray and Brian Vera as potential opponents on Aug. 3, according to Top Rank CEO Bob Arum.

Top Rank will pay for Manny Pacquiao and Brandon Rios to be randomly drug tested by The Voluntary Anti-Doping Agency, according to company CEO Bob Arum.

Manny Pacquiao is requesting random drug testing in advance of his Nov. 23 clash with Brandon Rios.

Mikey Garcia on his upcoming clash with Juan Manuel Lopez: "We both have power, so I think that the fans are definitely going to be looking forward to seeing a knockout on the night of the fight."

Freddie Roach said he gave Julio Cesar Chavez Jr. an ultimatum prior to ageeing to train him for his next fight on Aug. 3: "The first day that you miss, Julio, I can't tolerate that. I'm going to send you home or something."

Julio Cesar Chavez Jr. and Martin Murray could meet in a clash of once-beaten middleweights on Aug. 3 in Mexico City.

Brandon Rios on his November bout against Manny Pacquiao: "This is a very exciting fight for me. Not only for me, but also for the fans."

Brandon Rios says of his showdown with Manny Pacquiao: "We both like to fight. We both hardly back down. We both throw a lot of punches in bunches. So it's going to be one helluva good fight."

Manny Pacquiao will try to end a two-bout losing streak against 140-pound contender Brandon Rios, who will make his 147-pound debut against the Filipino hero on Nov. 23 in Macau in China, according to Pacquiao's promoter and advisor.

Abner Mares: "I actually added something different to my training camp, and it's called 'Mexican Judo.' It's 'ju-don't know if I'm going to box, or ju-don't know if I'm going to brawl, but you do know that I'm going to win.'"

Should Floyd Mayweather Jr. get beyond a May 4 date with Robert Guerrero at the MGM Grand, he could return to that site on Sept. 14 and go head-to-head with a potential clash between Tim Bradley and Juan Manuel Marquez.

Tim Bradley told ESPN that he ranks himself between Floyd Mayweather Jr. and Juan Manuel Marquez and ahead of Manny Pacquiao as the top fighters at 147 pounds.

A return bout between Sergio Martinez and Julio Cesar Chavez Jr. would have to include Olympic-style drug testing and take place either in Las Vegas, Atlantic City or New York, according to Martinez's advisor.

Once-beaten Argentine welterweight Luis Carlos Abregu, who has scored knockouts in five straight fights since falling to Tim Bradley by unanimous decision in July of 2010, has signed a promotional deal with Top Rank.

Middleweight contender Matthew Macklin claims that he will handle unbeaten WBA titleholder Gennady Golovkin in similar fashion to how Bernard Hopkins knocked out then-undefeated Felix Trinindad in the 12th round.

Unbeaten welterweight contender Kell Brook has suffered yet another foot injury that could jeopardize his scheduled challenge to IBF beltholder Devon Alexander for the third time.

Tim Bradley: "To be honest with you, I want Juan Manuel Marquez. I want the guy that beat Manny Pacquiao. Two guys that beat Manny, you know. Let's go at it. Let's settle it."

In accepting his award for Fighter of the Year, an emotional Nonito Donaire spoke of coming a long way since being the "small, frail, asthmatic little boy" of his childhood.

Top Rank CEO Bob Arum said that in the next few days he'll be meeting with fighters and their teams in New York, with the goal of selecting Manny Pacquaio's September opponent no later than Sunday.

Nonito Donaire on Saturday's clash with Guillermo Rigondeaux at New York's Radio City Music Hall:  "I owe New York a good fight. I know that my fans want a good fight, they're expecting a good fight, and that's what I want to give them."

Chinese two-time Olymic gold medalist Zou Shiming is primed for Saturday's pro debu in Macau.

Manny Pacquiao according to the Manila Standard: "I never avoid anyone. I don’t choose easy fights. I will fight anybody, anytime, anywhere."

Austin Trout: "Team Fight to Walk is very important to me. The statistics about number of everyday people and US troops impacted by Spinal Cord Injuries are scary."

RING junior featherweight champion Nonito Donaire takes on unbeaten WBA counterpart Guillermo Rigondeaux on April 13.

Top Rank CEO Bob Arum would like to "mix-and-match" Brandon Rios, Manny Pacquiao, Juan Manuel Marquez and Tim Bradley over the course of the next few months.

Bob Arum: "If the Nevada Commission has one standard of punishment for Americans, and one standard of punishment for Mexicans, then they should say that."

Manny Pacquiao's advisor said the rift between HBO and Golden Boy does not concern the fighter, and claims both Showtime and HBO are in the running to televise Pacquiao's next bout. Pacquiao's promoter Bob Arum says that's hogwash, the Filipino icon's next bout will be on HBO.

Paulie Malignaggi responds to AdrienBroner: "If he think that he's p---ed me off, all he's done with this talking like that, he has just put himself into the position where he has to fight. If he's 'A.B.,' and he's 'always business,' then stop being 'A.B.' the 'always bitching.'"

Adrien Broner says he has every intention to face WBA welterweight titleholder Paul Malignaggi on June 22. Said the brash WBC lightweight beltholder: "I'm (expletive) him up. (Expletive) Paulie. (Expletive) everybody that thinks Paulie's got a chance."

Tim Bradley on Ruslan Provodnikov: "Absolutely, I'm looking to make a statement in this fight. I'm looking to do some damage to this guy."

WBO welterweight titleholder Tim Bradley will be out to overwhelm March 16 rival Ruslan Provodnikov, who has served as a sparring partner for Manny Pacquiao and scored knockouts in four of his five straight victories. 

Golden Boy Promotions has big plans for Adrien Broner's next fight, which could be a 135-pound unificiation bout with Ricky Burns or a jump to welterweight to face Paulie Malignaggi, but the unbeaten WBC lightweight beltholder won't discuss his potential opponents.

Juan Manuel Marquez will consider a fifth fight with Manny Pacquiao, and if not, the Mexican legend will look at bouts against unbeaten boxers Tim Bradley or Brandon Rios, according to Bob Arum.

Junior flyweight Zou Shiming, a two-time Olympic gold medalist and three-time world amateur champion from China, will be making his professional debut on April 6 as part of a show that will be televised by HBO2 from Macao.

Unbeaten junior lightweight contender Diego Magdaleno believes that he can score his most definitive career victory against WBO beltholder Roman "Rocky" Martinez on April 6 in Macau, China.

Frank Espinoza, who manages two-division beltholder Abner Mares and WBC featherweight titleholder Daniel Ponce de Leon, says that a Mares-Ponce de Leon clash at 126 pounds could happen if Ponce de Leon defeats Jayson Velez on March 2.

Manny Pacquiao's advisor calls a fifth bout with Juan Manuel Marquez this year "a possibility," even as he says "other fighters are possibilities too."
