Sacked on Boxing Day, O'Driscoll may, incredibly, not come up against the man who took his place in the hotseat as Alex McLeish appears close to the City Ground exit himself.
A farcical transfer deadline day sparked reports of a bust-up between McLeish and the Forest board while results on the pitch have nosedived since the decision to axe O'Driscoll in the wake of a 4-2 win against Leeds United.
Bristol City are currently five points adrift of safety in the Championship after their defeat at Blackburn on Saturday.
