A few notes from around the boxing world:

• Former two-division titleholder Acelino “Popo” Freitas (39-2, 33 KOS), the Brazilian star who is coming out of retirement for the second time for a fight on July 18 in Sao Paulo, Brazil, announced that he will take on countryman Michael Oliveira (20-2, 15 KOs) in a rematch of Freitas’ ninth-round knockout win in June 2012. Freitas, 39, who won world titles at junior lightweight (where unified two belts) and lightweight, came out of his first retirement to face Oliveira, 25, who had been calling him out, and beat him at junior middleweight. Freitas retired for the first time after being stopped by Juan Diaz in their 2007 lightweight title unification bout.

• There was a purse bid scheduled for this past Friday for the mandatory fight between super middleweight titlist Badou Jack and George Groves. But the purse bid was called off because Jack promoter Mayweather Promotions and Groves promoter Sauerland Event reached an agreement, according to the WBC. However, there were no specifics on when and where the bout would take place. Las Vegas-based Jack (19-1-1, 12 KOs), who outpointed Anthony Dirrell on April 24 to win the belt, will be making his first defense against England’s Groves (21-2, 16 KOs), who has won two bouts in a row since back-to-back knockout losses to countryman Carl Froch in world title bouts.

• Top Rank announced on Tuesday that it has signed Sacramento, California, featherweight Guy Robb (15-1, 7 KOs) to a promotional agreement. Robb, who has won eight fights in a row since being stopped in the seventh round of a 2012 bout, is trained by Ray Woods, the stepfather and original trainer of the late lightweight and junior lightweight titleholder Diego “Chico” Corrales. “Guy has an aggressive, entertaining style of boxing and is always in exciting fights," said Top Rank’s Hall of Fame head matchmaker Bruce Trampler.
