Andy Murray, currently in Umag, Croatia for Great Britain's World Group Playoff tie, has said he wants more clarity with respect to the mysterious case of unconfirmed reports that Croatia's No. 1, Marin Cilic, failed a drug test in May.

The Independent reported yesterday that Cilic is in London to attend a hearing regarding his failed drug test. According to Croatian reports, Cilic failed a drug test in Munich, Germany due to high glucose levels after ingesting an over-the-counter supplement. The Daily Mailreports Cilic was prepared to tell an independent tribunal that his mother was to blame for the failed drug test, as she was the one who purchased the supplement.

"I think it's about time everyone knew what was going on," Murray said the night before his opening Davis Cup rubber against Borna Coric. "Everyone knows what's happening and he has clearly failed a drugs test, I just don't know why that can't come out. It's not that he's injured. I don't get that."

Cilic has not released a statement on the matter since news of the failed drug test hit Croatian media at the end of July; though he reportedly confirmed the news to his former coach Bob Brett. With the International Tennis Federation's policy of not commenting on doping cases until after an investigation and ruling has been completed, no official agency has confirmed the results of the test or the presence of an ongoing investigation. But Cilic, ranked No. 24, has not played since withdrawing from his second round match at Wimbledon, citing a left knee injury. In that span he has missed two ATP Masters 1000 tournaments and the U.S. Open, all mandatory tournaments.

"Once it's out in the open, then whether the hearing took two months or three or fourth months, so long as he isn't playing in that period [it doesn't matter]. I think it's too long for nobody to say he has failed a drugs test."
