There was no fairytale ending for four division world champion Miguel Cotto, who suffered a very unexpected upset decision loss to Sadam Ali (26-1) on Saturday night at Madison Square Garden in New York.

The curtain came down on Cotto's glorious 17-year career but not to script as Ali captured the WBO junior middleweight title before a shocked crowd that was filled with 12,391 fans - made up of largely of Puerto Rican fight fans who came to support the 37-year-old icon in his retirement fight.

Cotto (41-6), a 2008 Olympian, walked away in defeat via scores of 116-112, 115-113 and 115-113.

The end result was viewed as a huge upset to many experts and ringside observers.  

Ali was moving up from the welterweight division, had never faced anyone on the level of Cotto, and last year he was knocked out by Jessie Vargas - who is not regarded as a power puncher with only 10 knockouts in 29 fights. Ali was Vargas' first TKO win since 2011. 

After the loss Cotto revealed he suffered a bicep injury to his left arm during the fight.

While he didn't expect Ali to win, four division champion Roy Jones Jr. does not view the outcome as an upset.

"You can't consider that a huge upset, because let me tell you why.. because when you respect boxing and you have two Olympians in the ring together - anybody can win the fight. Now we didn't expect that Sadam was going to beat him, because Sadam lost to Jessie Vargas," Jones told BoxingScene.com.

"However, when Cotto tore his bicep during the fight in the seventh round, then Sadam Ali better win a decision or there is something wrong with him. You are an Olympian and a guy tore his bicep in his best arm, he's left handed, and he fights with that hand forward - you better beat him or there is something wrong with you. So no it's not an upset in my eyes."
