If all goes as expected, Juan Manuel Marquez will return to the ring on April 21 undefeated Argentinean César Cuenca (42-0, 1KO) in Morelia, Chiapas or Cancun. A source indicates the possibility of a vacant WBO junior welterweight title being at stake, although it's not exactly clear if the belt at stake will be the interim or the full title.

"All I know is that I'm fighting on April 21, but I don't know the opponent or the opponent. But if [the opponent] is Cuenca, then I'll have to look for him on Youtube, because honestly I don't know him and I've never seen him fight," Marquez said.

"Going by his record, I believe that he'll be difficult, a good boxer and fast. If he's ranked in the first position [by the WBO], he must have done something."

Marquez expects to fight three times in 2012, including a fight in July and then another contest in the fall - which he hopes is a fourth meeting with Pacquiao.
