Manny Pacquiao plans to fight Sugar Shane Mosley in his next bout May 7 in Las Vegas.

Promoter Bob Arum told the Associated Press that the deal will be done after Mosley’s lawyers approve the final paperwork for the welterweight fight at the MGM Grand Garden Arena.

Arum says Pacquiao chose the bout because Mosley is the most accomplished and famous boxer in the field of candidates, which included Juan Manuel Marquez and welterweight champion Andre Berto.

Arum realizes he could have trouble selling a fight against a nearly 40-year-old opponent who will be nearly 2 1/2 years removed from his last victory when he faces Pacquiao, but he believes Mosley’s skill and speed will challenge Pacquiao.
