A fighter as gritty as his North Philadelphia neighborhood, Gabriel Rosado will return to action Saturday night to launch the televised portion of Floyd Mayweather's pay-per-view bout.

The 27-year-old Rosado (21-6, 13 knockouts) will be the underdog against J'Leon Love (15-0, 8 KOs) in a 10-round middleweight bout at the MGM Grand in Las Vegas.

Mayweather (43-0, 26 KOs) will meet Robert Guerrero (31-1-1, 18 KOs) for the WBC welterweight title.

It is Rosado's first fight since a seven-round technical-knockout loss in January to power puncher Gennady Golovkin. Rosado fought on after two cuts near his left eye nearly blinded him early in the fight.

"I fought, I didn't quit," Rosado said. "I chalk it up like a man."

It is Rosado's second straight middleweight bout, and he said he has become more comfortable at 160 pounds since growing into the weight.

Garcia's next fight. Juniata Park's Danny Garcia (26-0, 16 KOs) will meet the winner of the Lamont Peterson-Lucas Matthysse fight on Sept. 7 at an East Coast venue. It likely means that Garcia will fight just twice in a calendar year for the first time in his career.

Peterson (31-1-1, 16 KOs) and Matthysse (33-2, 31 KOs), light-welterweights, will fight a 12-round bout May 18 at Boardwalk Hall in Atlantic City.

Hart in the spotlight. North Philadelphia super-middleweight Jesse Hart will return June 14 in a fight televised by ESPN from Stamford, Conn. The 23-year-old Hart (6-0, five KOs) will fight his second straight six-rounder and should have an opponent within the week.

"I'm going to try to end it as quick as possible," Hart said. "It will never go the six rounds."
