DeMarco Murray awaits NFL ruling

IRVING, Texas -- Dallas Cowboys players DeMarco Murray and Dez Bryant failed to present the proper identification necessary to take a mandatory drug test during training camp, the players confirmed to ESPN Dallas on Thursday.

Bryant, a second-year wide receiver, said that he has since taken the proper steps and has been cleared by the NFL and is not listed as having failed any tests. Two team sources also confirmed that Bryant has been cleared by the league.

Murray, a rookie running back, said he's taken all NFL-mandated drug tests since training camp, including one on Thursday afternoon, and said he's passed all of them.

However, until Murray is cleared, the league could consider the missed test at training camp a failed test. If Murray fails a second test, he is subject to a suspension and placement in the league's substance abuse program.

A failure to present ID is treated as a failure to cooperate with testing. But each case is reviewed, and depending on the circumstances, the player could be warned, placed on reasonable-cause testing (steroid policy), subjected to evaluation and placement into the drug treatment program (drug policy), or disciplined (if already in the program and/or failure was intentional effort to avoid testing).

Murray said he has a scheduled conference call with league officials Thursday night to clear up his issue.

"I have taken the tests three times a week," Murray said. "I met with a [counselor] this past week. I have a conference call today to get me off the list. I have never failed a drug test."

If the league doesn't rule in favor of Murray, he will go into the NFL's drug treatment program.

Cowboys and NFL officials are not permitted to comment on players regarding the substance abuse policy, citing confidentiality rules.
