A few notes from the boxing world:

• The Brandon Rios-Diego Chaves welterweight fight on Aug. 2 (HBO) now has a site: The Cosmopolitan in Las Vegas.

• Former super middleweight titleholder Robert Stieglitz (46-4, 26 KOs) returns on July 26 in Dessau, Germany, according to promoter SES Promotions. His opponent has not been determined. The fight will be Stieglitz's first since losing his 168-pound by split decision to Arthur Abraham in their rubber match on March 1.

• Heavyweght contender Vyacheslav "Czar" Glazkov (17-0-1, 11 KOs) returns to action to headline a card on Aug. 9 (NBC Sports Net) at the Sands Resort in Bethlehem, Pennsylvania, according to Main Events. His opponent has not been determined.

• Golden Boy has added bantamweight titlist Tomoki Kameda (29-0, 18 KOs) of Japan in a defense against Pungluang Sor Singyo (46-2, 31 KOs) of Thailand to the July 12 Canelo Alvarez-Erislandy Lara undercard at the MGM Grand in Las Vegas. Kameda-Singyo, however, is not slated to be part of the Showtime PPV telecast.

• Cleveland junior middleweight Willie Nelson (22-1-1, 13 KOs) has signed with manager Cameron Dunkin, who has had a long relationship with Nelson's trainer, Jack Loew. Loew trained former middleweight champion Kelly Pavlik, whom Dunkin managed for his entire career.

"I feel like Cameron is the missing piece in my team. He's the person that can get me the fights and exposure I need to move forward in my career," Nelson said.

Nelson returned from a year layoff following left elbow surgery on the June 7 Miguel Cotto-Sergio Martinez undercard to score a first-round knockout of Darryl Cunningham.

• England's Frankie Gavin (19-0, 12 KOs) will challenge Italy's Leonard Bundu (30-0-2, 11 KOs) in a battle of southpaws for Bundu's European welterweight title on Aug. 1 in Wolverhampton, England, promoter Frank Warren announced on Thursday.

"He's a good fighter and I'd be stupid to underestimate him," Gavin said. "He beat [former world title challenger Lee] Purdy in a tough hard fight over here [in England in December] so he'll have no second thoughts about fighting me in front of my home crowd. He'll have my full respect and I'm preparing for a hard 12 rounds. Either way, if it goes the distance or I stop him, I'll be leaving the ring the winner.

"He's a short, compact fighter and has good all-round skills. It will take a great fighter to beat him and I'm very confident in my skill and ability to be the man to beat him for the first time. Bundu's got good fitness for 39, but he's not like he was when he was 30 and you don't know how much the Purdy fight took out of him. I'm not 30 yet and I believe I'll have the advantage as I'm younger and fresher."
