Miguel Cotto Sr., the father of former two-division titleholder Miguel Cotto, passed away at the age of 57 in Puerto Rico on Sunday morning, the apparent victim of a heart attack, according to El Nuevo Dia.

The the Puerto Rican daily newspaper reported that Cotto Sr., who suffered from health problems such as asthma and sometimes needed the assistance of an oxygen tank to assist his breathing, was driving early Sunday, felt ill, stopped the car and reportedly asked for help before collapsing.

Cotto Sr., who served in the Puerto Rican National Guard for 25 years and worked Cotto's corner during the fighter's loss to Manny Pacquiao on Nov. 14, was very close to his son.
