Former Bulls loanee Mark Marshall has been provisionally suspended by Barnet after failing a drugs test.
The winger, who joined the Bulls on loan from Swindon in 2009, had missed the Bees' last two matches with speculation hinting at a transfer window move to one of a number of Championship sides.
However a statement by Barnet today says Marshall was tested after their Boxing Day match with Dagenham and failed for a prohibited substance. The statement adds that Marshall says he had unwittingly taken the banned drug as part of a supplement.
The FA are yet to make a statement on the matter, but a lengthy ban is likely.
Meanwhile, the Bees have released another ex-Bull. Anwar Uddin, who played ten times for the Bulls in the 03/04 season, had previously captained both the Bees and Dagenham, where he helped them to promotion to the League. The 30 year old has not played for the Bees' first team since October.
