Filipino southpaw Manny Pacquiao will return to the ring in the second week of December for a fourth battle against long-time rival Juan Manuel Marquez of Mexico.
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.
Pacquiao (54-4-2, 38 knockouts) has fought just once since then, surrendering his WBO welterweight title on a hotly disputed split decision to American Timothy Bradley in Las Vegas in June.
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.
The Mexican then lost his WBC super-featherweight title to the Filipino in a controversial one-point split decision in March 2008.
