Last night in Durango, junior middleweight contender Omar Chavez (36-5-1, 24 KOs) once again suffered a career setback when he lost a ten round unanimous decision to underdog Jose Carlos Paz.

Chavez was already coming off a ten round decision loss from last August, at the hands of Roberto Garcia.

Last April, Chavez's career was riding high after scoring a two round stoppage of Ramon Alvarez, who is the older brother of superstar Canelo Alvarez. The win was a rematch of their 2014 clash, which saw Alvarez win a decision.

Last week, Omar's famous father - Julio Cesar Chavez Sr. - made it public that he issued an ultimatum to both of his sons. He advised them to start taking their careers seriously or retire immediately.

Rodolfo Chavez, who is the brother of Chavez Sr. and the head trainer of Omar Chavez, was shaking his head at the outcome.

"It was disappointing, why lie," acknowledges Rodolfo to Juan Manuel Vazquez.

"He trained very well and he has a lot of good fights he can make. But when it comes to being in the ring, he's in a spell, like Chavez Jr. was against Canelo... that's what it reminded me of."

Rodolfo says that his brother, Chavez Sr., was enraged by what his son was doing in the fight with Paz or Argentina.

"He walked away angry, as if he's tired of seeing the same thing, over and over again, with his two children," Rodolfo said.

Rodolfo did not have any discussions in the aftermath with Chavez Sr. or Omar.

He says it's very difficult to work as the head trainer of Omar and Chavez Jr.

"It's hard to be in their corner, because you have to do the work and also be family. But it's like the passion is gone and something goes through their heads, but only they know what it is," says the coach.

In the upcoming week, Rodolfo will travel to Tijuana to join the team of Chavez Jr., who wants to return to the ring in the coming months.

"He has not stopped training, but he has to put the batteries in gear - because they are many years of carelessness in his career," Rodolfo said.
