Marquez's wife rules out return

Have we seen the last of Juan Manuel Marquez inside a boxing ring?

The Mexican boxer, fresh from his sensational sixth-round knock out of Manny Pacquiao, may be calling it quits following a promise he made to his wife before the bout.

Speaking to the press Saturday at an official reception hosted by Mexican president Enrique Pena Nieto, the 39-year-old said as of now he would "like to rest and I couldn't tell you if there was going to be another fight."

Marquez reveals he told his wife that" regardless of the result, it would be my last one. The day I arrived in Mexico City I asked her to give me the chance to fight one more fight. And she said 'No. You promised you would retire.'"

But with Pacquiao and promoter Bob Arum both openly pushing for a Pacquiao-Marquez V, a fight which could potentially fatten Marquez's bank account, the Mexican warrior might just change his mind.

If ever a part five does happen, it can only take place after Pacquiao serves the mandatory 120-day suspension levied by the Nevada State Athletic Commission on all boxers who lose by knockout. This includes a moratorium on any form of boxing training for 90 days, meaning the earliest realistic date that Pacquiao can fight again will be around May.

But since the 2013 elections are scheduled on May 13, a better date would probably be around June. That gives Marquez an extra few weeks to convince his wife to change her mind.

However, trainer Freddie Roach has said he prefers a September comeback for Pacquiao. But all this will be moot if Marquez can't get clearance first from his wife.
