Add Cain Velasquez to the list of UFC fighters to defend the idea of stricter doping tests within the organization. 

Currently, fighters are tested through urine samples, but the heavyweight champion believes that exams should be done through blood tests more frequently, and even by surprise.

“There are rules,” Velasquez said. “We all must follow the same rules.”

The champ shares this opinion with UFC fighters like Junior dos Santos, Georges St-Pierre, Benson Henderson and Daniel Cormier. For them, it’s possible to compete at a high rate without the use of anabolic steroids. For Velasquez, the seriousness in controlling the tests will disallow opponents who use illegal substances from taking advantage of him in a fight.

“I’m a natural athlete,” he said. “All my opponents should be the same way. It is not fair that those (fighters) have an advantage.”

When asked of teammate Lavar Johnson, who was recently cut by the UFC after a drug test showed high levels of testosterone following his UFC 157 fight, the champion did not hesitate.

“I feel good that the tests are being done more often,” he said. “My thought is to be natural, not doped … Those who don’t follow it will be out.”

Riki Fukuda and Alex Caceres failed their drug tests following their March 3 bouts at UFC on Fuel TV 8, according to a statement made Wednesday by UFC officials.

As a result of the failed tests, Fukuda has been released by the UFC, while Caceres will face a six-month suspension.

Fukuda’s results showed the presence of phenylpropanolamine, norpseudoephedrine and ephedrine, which are all considered banned substances by the organization. The results of his test will be reported to the official Association of Boxing Commissions record keeper, company officials said.

Caceres tested positive for marijuana metabolites following his bout, and he has agreed to attend drug rehabilitation classes. His six-month suspension  is retroactive to the date of the event, and he must pass a drug test upon completion of the suspension before receiving clearance to fight again. The outcome of Caceres’ fight against Kyung Ho Kang will be changed from a win to a no-contest.

The failed tests add to the growing number of UFC fighters testing positive for banned substances. The California State Athletic Commission (CSAC) yesterday told MMAjunkie.com’s Steven Marrocco that UFC heavyweight Lavar Johnson tested positive for elevated levels of testosterone following his UFC 157 loss to Brendan Schaub. An additional test, a CSAC representative said in the report, showed Johnson’s testosterone was consistent with the administration of a steroid.
