WBC middleweight champion Miguel Cotto has absolutely ruled out the possibility of a trilogy bout with Mexican rival Antonio Margarito.

The boxers first me in 2008 in Las Vegas, where Margarito handed Cotto his first professional defeat with an eleventh round knockout.

A rematch was scheduled for December of 2011, where Cotto won with a ninth round stoppage. It was Margarito's final fight before he announced his retirement due to issues with his right eye, which he first injured in a 2010 defeat to Manny Pacquiao. The eye tremendously swelled against Cotto and led to the doctor stopping the fight.

In-between those two fights, Margarito was involved in one of the biggest boxing controversies in the last 20 years, when hard illegal inserts were discovered in his hand wraps only a few hours prior to a scheduled January 2009 showdown with Shane Mosley, who knocked the Mexican veteran out in nine round.

Margarito suffered a suspension, fine and returned the following year.

A few months ago, Margarito revealed that he plans to return to boxing. He already sat down with promoter Bob Arum of Top Rank to plan out his comeback and he traveled over to Utah to receive a positive medical analysis on the right eye.

Among the opponents being targeted by Margarito is Cotto.

Cotto has ruled out any possibility of a third fight. He believes Margarito loaded his gloves with those illegal inserts for their meeting in 2008 and failed to prove his innocence by being dominated and stopped in the rematch. Though it should be noted that Margarito was starting to get a rhythm going when the fight was stopped by the ringside doctor.

"Margarito already had his chance to show the entire world that he didn't have anything in his wraps in our first fight, which as we all know wasn't the case, and he failed [in proving that in our rematch]," Cotto told Rigo Cervantez.
