Ex-Wales rugby captain Mike Hall has resigned from the Cardiff board ahead of the club's forthcoming legal battle.
Hall is confident that Cardiff will win their court case
Cardiff are due in court on 21 November in a dispute with financial backers Langston over £24m of loan notes.
Should the Bluebirds lose, Hall would face a conflict of interest as he is also a director of PMG Associates, another of the club's major creditors.
"It's disappointing, but I had to resign on legal advice," Hall told BBC Sport Wales.
"We're very confident of winning the case, but we have to have a back-up plan - that's good corporate management."
Hall's departure leaves Steve Borley, Alan Whiteley and chairman Peter Ridsdale as Cardiff's surviving directors.
