Barnet winger Mark Marshall has been given a two-year suspension after failing a drugs test in December.
He tested positive for the stimulant methylhexaneamine following
the League Two match against Dagenham & Redbridge.
The 25-year-old has not played since 14 January after he was given
a provisional ban.
A statement from the FA
said: "Mark Marshall has been suspended by an Independent Regulatory Commission from all football activity for two years."
The former Swindon player "
will be looking towards launching an appeal
" against the decision, according to the club's official website.
His two-year suspension dates back to the start of his provisional ban from 20 January.
Marshall joined the Bees from Swindon in July 2010 and scored three goals this season.
