The controversy continues over Saturday's fight between Julio Cesar Chavez Jr. and Marco Antonio Rubio. Chavez Jr. won a twelve round unanimous decision over Rubio at the Alamodome in San Antonio, Texas.

Chavez, who weighed in at 159.5 at Friday's weigh-in, came to the ring at 181-pounds. The Mexican champion admits that he really struggled to make the weight.

Rubio and his team are protesting the pre-fight actions by the World Boxing Council, claiming the organization forgot to implement the post-fight anti-doping tests for the two boxers. Rubio's team is alleging that Chavez left the venue to avoid taking an anti-doping test, and they believe the Mexican champion was possibly under the influence of a banned substance.

Rubio's promoter, Reginaldo Kuchle, said the following - "In the ninth round, Rubio told me that it felt like he was fighting a heavyweight. I can't accept that Chavez fought with such energy and never tired. There were rounds where he didn't even sit on his stool. A test should be performed. If a boxer ingested a forbidden substance, it takes days to remove it. That is why if this test needs to be done and there is still time to carry it out. If he doesn't take it, then it increases the suspicion that Julio ingested or injected something."

The World Boxing Council doesn't understand why Rubio and his team are involving their organization in this controversy.

The WBC have advised Rubio and his promoter to take their dispute to the Texas Athletic Commission. The WBC emphasized that the local commissions are in charge of hiring the laboratory to administer the anti-doping tests on the fighters.

"We are not responsible for that review. If a drug test was not performed, that is something that always corresponds to the local commissions - which in this case was the responsibility of the Texas commission and not the World Boxing Council. The WBC can not get involved in the internal affairs of the commissions. It is up to Texas to respond to those claims."
