A few notes from around the boxing world:

• Top Rank has rounded out its portion of the non-televised card on the Floyd Mayweather-Manny Pacquiao show on May 2 at the MGM Grand in Las Vegas. It will pit welterweight Brad Solomon against Adrian Granados in an eight-rounder, according to Top Rank vice president Carl Moretti. Solomon (24-0, 9 KOs), 31, of Lafayette, Louisiana, is a former amateur standout who has been biding his time on undercards while Top Rank tries to line up a meaningful fight for him. Granados (13-3-2, 9 KOs), 25, of Chicago, is an aggressive fighter but is coming off a 10-round majority decision loss to 2008 Dominican Olympic gold medalist Felix Diaz in November. Top Rank's other non-televised bout pits super middleweight prospect Jesse Hart against Mike Jimenez in 10-round fight. Mayweather promotions also has two non-televised bouts lined up: junior middleweight prospect Chris Pearson against Said El Harrak in a 10-rounder and cruiserweight prospect Andrew Tabiti against Anthony Caputo Smith in an eight-round fight.

• In anticipation of the May 2 pay-per-view showdown between Floyd Mayweather and Manny Pacquiao, HBO commentators Jim Lampley and Max Kellerman will host a special roundtable discussion featuring an elite group of fighters who have gone toe-to-toe with both Mayweather and Pacquiao. "Mayweather/Pacquiao: The Legends Speak" debuts Saturday night (approximately 12:15 a.m., following the network's live coverage of heavyweight champion Wladimir Klitschko's defense against Bryant Jennings at Madison Square Garden in New York. The half-hour show includes interviews with four of the five of the common opponents Mayweather and Pacquiao share: Oscar De La Hoya, Shane Mosley, Miguel Cotto and Ricky Hatton. Also, Kellerman will anchor a roundtable discussion with three fighters who know what it's like to prepare for a super fight: George Foreman, Lennox Lewis and Bernard Hopkins.

• Hall of Fame former super middleweight champion Joe Calzaghe will serve as a guest analyst for the Spike TV-televised "Premier Boxing Champions" card on April 24 at the UIC Pavilion in Chicago. Calzaghe, who retired undefeated (46-0, 32 KOs) in 2009, will feel at home calling the main event, a super middleweight world title bout between Anthony Dirrell (27-0-1, 22 KOs) and challenger Badou Jack (18-1, 12 KOs).

• Heavyweight contender Steve Cunningham (28-7, 13 KOs), 38, of Philadelphia, a former two-time cruiserweight titlist, has signed with adviser Al Haymon. "I'm looking forward to working with Al," he said. "I've been watching him for several years and seeing all that he accomplishes for his fighters but have always been on the outside looking in due to contractual obligations. It finally lined up to where we can work together and it's going to be great. I believe my best fights have yet to be seen." In Cunningham's last fight, on March 14, he lost a controversial decision to Vyacheslav Glazkov in a world title elimination bout.
