LAS VEGAS — Filipino southpaw Manny Pacquiao will return to the ring on Dec. 8 for a fourth battle against long-time rival Juan Manuel Marquez of Mexico, the fight's promoters said Friday. The two fighters, who last met in November when Pacquiao beat Marquez with a controversial majority decision, will meet at the MGM Grand Garden Arena in Las Vegas, Top Rank said in a statement. Pacquiao (54-4-2, 38 knockouts) has fought just once since then. Marquez (54-6-1, 39 KOs) and Pacquiao are renowned for their aggressive approach in the ring and they fought to a draw when they first met in May 2004. — Reuters
