Julio Cesar Chavez Jr. took a humbling loss to Andrzej Fonfara in their 12-round light heavyweight showdown on Saturday, but the Mexican boxing superstar did not walk away empty-handed.

Chavez, who took the second defeat and first knockout loss of his career, showed off his paycheck through a post on his Instagram account. The photo, which showed Chavez's $1.75 million paycheck, was deleted moments after he posted it on social media, but Yahoo Deportes managed to get a copy of the photo.

The son of Mexican boxing icon Julio Cesar Chavez Sr. was a heavy favorite to win in his first fight since scoring a unanimous decision win against Brian Vera in March last year, but Fonfara managed to prove his doubters wrong.

Fonfara took control of the fight and landed solid punches that made Chavez bleed from his nose and were enough to inflict serious damage around the eyes of the former world middleweight champion.

Fonfara, who improved to 27-3 with 16 knockouts, knocked Chavez down for the first time in his career when he landed telling blows in the ninth round of the fight.

Following the knockdown, Chavez quit on his stool and claimed to trainer Joe Goossen that he suffered a leg injury, but most analysts are convinced the Mexican knew he could not take more blows anymore if he decides to continue.

Fonfara said that he was confident he would win the fight since the opening round of the bout. He expected a tough opponent in Chavez, but Fonfara hinted that he figured out in the first round that he could take even the heaviest punch of his heavily favored opponent.

"I know Chavez is tough fighter. He don't quit. He's in good shape. But what I saw in the first round, I knew I would win this fight," Fonfara told reporters. "He hit me with one good punch, I catch it, and I say this guy doesn't have punch because he hit me as hard as he can."

Chavez admitted after the fight that Fonfara was too big and too heavy for him as the fight was arranged at a catchweight of 172 pounds. The Sinaloa, Mexico native had his best years a professional boxer at the middleweight division, which has a 160-pound limit.

But despite admitting that his opponent was just simply too much for him, Chavez also took a swipe at some tactics of Fonfara. In a video posted on his Instagram account, Chavez indicated Fonfara used some dirty tactics against him, which he said was the reason why he decided to enter boxing, not American football.

"That's why I never played American football," Chavez wrote.
