TENNIS: Andy Murray believes there are no excuses for athletes accidentally taking a banned substance and that Viktor Troicki and Marin Cilic were "unprofessional" in the actions which led to their recent suspensions.
He said: "You need to know the rules. I personally myself would never go and buy something over the counter in a pharmacy – it's just unprofessional.
"Any supplement that you're taking, whether it's a protein shake or fish oils, or anything like that, you get it checked.
"We are professional athletes now - there's no excuses.
"I think 10 or 15 years ago, when people didn't think drug-taking happened in sport, then people might have thought 'yeah, we can just buy stuff over the counter in any old pharmacy' but look, we can't do that."

Dale Steyn then claimed career-best figures of five for 25, as he effectively derailed Pakistan's pursuit with three wickets in the 47th over.
