Miguel Cotto, Puerto Rico’s only four-division titleholder and a future Hall of Famer, will return to the ring this fall.

The date, location and opponent have not been determined, but Michael Yormark, president and chief of branding and strategy for Roc Nation, said on Tuesday that Cotto’s return is in the works.

Although Yormark was speaking on a media teleconference with light heavyweight contender Andre Ward to promote Ward’s Aug. 6 HBO main event against Alexander Brand, Cotto’s name came up.

“We are hoping to have Miguel back in the ring before the end of the year,” Yormark said. “We’re working on that now. We’re hopeful to have some kind of an announcement over the next couple of weeks.”

Cotto, 35, has not fought since losing a decision and the middleweight world title to Canelo Alvarez in their Nov. 21 pay-per-view showdown. There was discussion that Cotto, who likely will move down to the junior middleweight division where he once held a world title, would return in June, but he opted to sit out until the fall.

Cotto (40-5, 33 KOs) has one fight remaining on his promotional contract with Roc Nation Sports.

Juan Manuel Marquez, the Mexican star and former four-division titleholder, is one of the leading possibilities to face Cotto. He is also the most realistic opponent for Cotto if he wants to do a major pay-per-view fight. Names sell, and they are both big names with the additional carrot of the great Puerto Rico versus Mexico rivalry as a backdrop.

The 42-year-old Marquez (56-7-1, 40 KOs), who has won world titles at featherweight, junior lightweight, lightweight and junior welterweight (and also owns a brutal knockout of Manny Pacquiao in a nontitle welterweight fight), has not fought since winning a unanimous decision against Mike Alvarado in a May 2014 welterweight title eliminator, mainly because of a knee injury.

“We’re looking at a couple of opponents, but it’s too early to disclose who we’re talking to,” Yormark said.

However, according to a source with knowledge of the discussions, the Cotto and Marquez camps have been talking about a deal. The primary issue, however, is not money; it’s the contract weight. Cotto, according to the source, does not want to drop below 150 pounds; Marquez wants the fight at the welterweight limit of 147 pounds.

Cotto has weighed 153 ½ pounds for his past two fights and has not fought as a welterweight since he got knocked out by Pacquiao in the 12th round of their 2009 world title fight.
