This has been talked about for a while, but it appears closer to actually happening than most people thought. Manny Pacquiao has said almost immediately he wanted to fight in April and now Juan Manuel Marquez has said according to Boxing Scene that he will continue to fight and also plans to take a bout in April.
Rumored opponents could be Jessie Vargas (a former Mayweather protege who is now with Top Rank) and Vyacheslav Senchenko (who knocked Ricky Hatton, back into retirement).
Freddie Roach thinks it is a bad idea for Pacquiao to fight so soon, but since Pacquiao is his boss he doesn’t have much say in the matter.
The fights could be on the same card. They are looking at locations overseas before coming back to the states for their 5th fight.
