By Allan Fox: WBC middleweight champion Julio Cesar Chavez Jr. may have tainted his own victory over Marco Antonio Rubio by failing to stick around and take the mandatory urine test after the fight to test for performance enhancing drugs.

According to fightnews.com, Team Rubio isn’t pleased about Chavez Jr. leaving without being tested and they plan on filing an appeal. The skipping out on the test by Chavez Jr. has more than a few boxing fans wondering how this could have happened, as Chavez Jr. had fought professionally 46 times before last nights’ fight and he should know the drill after all those fights.

And if Chavez Jr. forgot, certainly his trainer Freddie Roach should have known that Chavez Jr. needed to be tested, shouldn’t he? Is Roach forgetting those things as well? WBC president Jose Sulaiman is saying “We forgot,” according to fightnews.com. So the WBC is making excuses for Chavez Jr? I guess the WBC also forget to make Chavez Jr. fight Sergio Martinez as well after originally saying he had to defend his title against Martinez.

Why it looks bad is because Chavez Jr. came in 21 pounds over the middleweight limit of 160 on the night of the fight after having made weight at 159.5 the day before, meaning that Chavez Jr. had put on 21.5 pounds through rehydration after the weigh-in. But then he reportedly fails to take the urine test for performance enhancing drugs after the fight. You can see why this might taint the victory in the eyes of a lot of boxing fans.

The WBC needs to make sure that Chavez Jr. is tested in order for Team Rubio and boxing fans to have faith that there wasn’t anything suspicious going on with Chavez Jr. last night for him to skip a urine test that he’s taken many times in the past. The WBC needs to try and bring Chavez Jr. back so that he can be tested. If not, that puts things in a weird situation where a champion can fight without being tested. It kind of makes a mockery of the rules.
