Barnet winger Mark Marshall has been banned for two years by the Football Association after failing a drugs test.
The 25-year-old tested positive for Methylhexaneamine following the League Two side's match against Dagenham & Redbridge in December.
He was provisionally suspended by the club in January.
Marshall, who signed for the Bees in 2010, will not be able to return to action until 2014.
