Saul “Canelo” Alvarez will be shut down for the rest of the year with a fractured right thumb.

Golden Boy announced that their most profitable and popular fighter will not be able to fight for the rest of the year. He broke his thumb defeating English junior middleweight star, Liam Smith, on Saturday. Alvarez, who is of Mexican descent, attracted over 51 thousand fans to the AT&T Stadium in Arlington, Texas and was hoping to fight again at the end of the year.

According to Alvarez, the injury occurred in round two of the fight. Alvarez arrived at the postfight press conference with a bandage wrapped around his right hand but did not think he had broken it. Alvarez did, however, admit that he was affected by the injury in the fight. He claimed to rely more on his left hand after hurting his right.

“After I got hurt I probably used my left hand a little more and went to the body a little bit more, but [going to the body] was part of the game plan,” said Alvarez. “I’ve always said you have to be prepared for anything in that ring, and that’s what I was. I was prepared for anything.”

Alvarez, who is the lineal middleweight world champion, was diagnosed on Monday by Dr. Pedro Jaime Lomeli in Guadalajara, Mexico.  Stefan Friedman, Golden Boy spokesman, reported that after x-rays and a CT scan it was confirmed that Alvarez had suffered an avulsion fracture of his right thumb.
