Top Rank's CEO Bob Arum is shocked with the recent news that five fighters involved with last Saturday's card at the WinStar Casino in Thackerville, Oklahoma, were placed on suspension by the Chickasaw Nation Boxing Commission for failing drug tests. Tommy Zbikowski, heavyweight Andy Ruiz Jr., John Jackson, Terrance Roy and David Robinson were all placed on suspension. All five fighters tested positive for marijuana.

"I think that it's a flaw in the testing, but I don't know. That indian tribe must have some sort of special testing. I've never seen or had or heard of an event where so many guys tested positive for marijuana. I mean, it's crazy. See, in most states, the bar is elevated as far as testing for marijuana. You know, that's significant here [in Las Vegas.] But it is what it is. None of these guys tested for significant amounts of anything," Arum told BoxingScene.com

Mike Joyce, Zbikowski's attorney and adviser, told BoxingScene.com that his client is going to set the record straight as soon as possible.

"We're sending Tommy to an independent lab today, and I know that their test will not come back instantaneously. This test will be taken somewhere in the Chicago area I suppose," said Joyce. "But we're definitely appealing it. It's very shocking that so many people tested positive for marijuana. I've never seen that many people have a positive test at a boxing show before."

"Tommy has been tested hundreds of times for drugs throughout college and in the professional football ranks, and he's never tested positive for anything. Ever," said Joyce. "I wasn't even there for the drug test. I didn't find out about it until the next day."

"They said that the test is supposed to take a couple of hours," said Joyce. "I think that he was expecting to take it at 2 p.m."
