Premiership star 'tests positive'
The Mail on Sunday has reported that a Premiership player tested positive for a "banned substance".
Neither the player nor the club can be named for legal reasons, and the Football Association refused to comment on the report on Sunday.
The FA said it was tightening its doping programme after Rio Ferdinand's missed drugs test in 2003.
It said in July it would increase the number of tests in the 2004-05 season by 20% after a review by Lord Coe.
