Julio Cesar Chavez Jr was routed on Saturday night and stopped for the first time in his pro career, as the Mexican star quit following the ninth round, when he was dropped by Andrzej Fonfara, another first for Chavez.
Chavez (48-2-1, 32 KO) was ripped by a left hook from Fonfara (27-3, 16 KO), which sent him tumbling somewhat awkwardly to the canvas, and though he got up and continued for the remainder of the round, he was looking pretty clearly finished after what had been a very long night for him, with Fonfara beating up on him for the majority of the fight.
Fighting at a 172-pound catchweight against a fighter who has been at light heavyweight for five years, Chavez lacked his usual size advantage on fight night, and it showed up in his power (which seemed nonexistent) and his ability to take big shots (which was far below what we've seen him do at 160).
After the fight, Chavez claimed he was winning the fight (he wasn't), and that he'd like a rematch at another catchweight, 170 pounds, because he feels that maybe if he can drain Fonfara further, he might be able to compete with him. It's sound logic.
