Antonio Margarito calls it quits

Antonio Margarito, "The Tijuana Tornado," announced his retirement Thursday, ending a controversial boxing career that ended in losses in three of his final four fights.

"After 22 years of full dedication to the profession I love, I have made the decision to announce my retirement from boxing. After much thought and extended conversations with my family and team, we have all agreed that the time to hang up my gloves and begin a new chapter in life has arrived," Margarito said.

Margarito, from Mexico, was infamously suspended for 16 months after a substance was found inside the boxer's gloves prior to a fight against "Sugar" Shane Mosley in January 2009.

The ordeal came six months after Margarito scored a TKO over Miguel Cotto to capture the WBA welterweight title. Cotto enacted revenge last December in a one-sided rematch in what proved to be Margarito's final bout.

Margarito, 34, finished his career with a 38-8 record and 27 knockouts.
