He's taking on Ali at Madison Square Garden in New York City.
It hadn't. Indeed, Ali won the final four rounds on all three judges' cards.
"Thank you for supporting me at every opportunity", Cotto told his fans. "Something happened to my left bicep, seventh round".
"I don't want to make excuses", he said. It is my last fight. I am good, and I want to be happy in my home with my family, said Cotto who is a six time champ and a belt holder In four different weight divisions. He landed a sharp right-left combination to end the fight.
The 37-year-old had announced before the fight that his defence of his WBO light-middleweight title would be the last time he would enter the ring. He is the only Puerto Rican man to do so, despite the island's rich boxing history. Not least the oddsmakers, who installed him as a 6-1 underdog.
Ali was moving up in weight for the biggest fight of his career.
Sadam Ali realizes some of his doubters will begrudgingly give him credit.
"I worked hard for it". Even in the post-fight, he reiterated that he's done for good. Ali wobbled Cotto in the 2nd with a stunning straight right but seconds later went down via a slip to kill any momentum he may have had.

Saturday night mark the end of the road for Miguel Cotto.
After Cotto cruised through the first round to chants of "Cotto!" Cotto attempted to use his work rate and superior size advantages over Ali, however this was negated well by Brooklyn's Ali. Yet, it was Vargas who looked the worse when they left the ring.
"I had him hurt here and there", Ali said.
"I enjoyed my whole career, and I can't point at one fight". Ali moved away, smiling, but he was hurt from the shots. Ali stemmed the tide in the eighth round, finding the bounce in his legs again and not hesitating to let his hands go and trade punches with the fighter eight years his senior. Cotto, his face showing damage, tried to keep Ali off with his jab, but Ali was much busier as he chased after him.
Ali's hand speed proved troublesome for Cotto.
"Whatever [Golden Boy Promotions] has next, I'll take it".
"Good things happen to good people", Ali said. "I'm so glad to call Madison Square Garden my home". "But this is the opportunity of a lifetime, and I took the challenge against a legend", Ali said.
After the fight, the crowd lingered for a video presentation of Cotto's career highlights on the JumboTron.
