20 positive tests of fighters in both boxing and Mixed Martial Arts with 90% of the positive drug tests coming from Mixed Martial Arts fighters. These were the results and yeah there is a problem here. And the problem is not isolated to lesser known fighters. Ultimate Fighting Championship star Royce Gracie tested positive for a steroid after winning a fight earlier this month and could face a year's suspension, the head of the California Athletic Commission said Friday.

The 40-year-old Gracie tested positive for a nandrolone metabolite steroid after beating Kazushi Sakuraba in a June 2 match at the Los Angeles Memorial Coliseum.

Gracie will be suspended and fined up to $2,500, but has 30 days to appeal the decision, said Armando Garcia, the panel's executive officer. Gracie will appeal the decision.

"I will appeal the decision for sure, I have been a fighter for 14 years and have never taken any illegal substances, so I am sure this is just a misunderstanding."

The news comes following allegations that big name UFC fighter Chuck Liddell had just come out of rehab for a substance abuse problem.

Earlier it was announced that two other fighters on the card also tested positive for drugs.

Tim Persey tested positive for methamphetamine. He was suspended for six months and fined $1,000 pending appeal, Garcia said.

Results of a test taken before his fight indicated that former NFL receiver Johnnie Morton had a high level of testosterone, indicating he had abused a steroid before the contest, Garcia said.

He declined to take a post-fight "drugs of abuse" test and was suspended indefinitely by the athletic commission, Garcia said.

It was the second time in a week that a fighter has been identified as testing positive for steroids.

The athletic commission said Wednesday that three-time champion James Toney and Danny Batchelder, his opponent in a heavyweight boxing match May 24 in San Jose, tested positive for steroids. They were suspended indefinitely.

Michael David Smith of AOL Sports writes:

"UFC often doesn't have drug tests, and that has the potential to tarnish the sport's image. If mixed martial arts is ever going to shed the "human cockfighting" label once and for all, it has to be perceived as clean, and that will only happen when every single competitor is tested."
