The on-site doctor for CBS' Survivor, Adrian Cohen - you've seen the hunky Aussie rush to help several injured players, and on Oprah, among other places - has admitted to an Australian medical tribunal that he used cocaine to combat stress on the job. He's also accused of inappropriately obtaining prescription drugs and allegedly distributing them on Survivor and other shows. Survivor host Jeff Probst tells TV Guide that Cohen "has always been very professional. A very experienced emergency doctor, he's helped me on several occasions, helped most of our crew and castaways.... And many times he is the first guy helping locals in some pretty remote places."

So will the globe-trotting doc himself be snuffed? Exec producer Mark Burnett, who also worked with Cohen on Eco-Challenge, will await the verdict of the tribunal before taking any action. - Reporting by Ileane Rudolph
