Albion supporters have already snapped up almost 2,000 fans for the trip to the City Ground, and another 1,000 tickets have been made available.
The fixture has further resonance as Forest have leapfrogged Albion into the play-off spots after an incredible run of six straight wins under returning boss Billy Davies.
However Gus Poyet’s men will enter the fixture buoyed by the recent 3-0 triumph over rivals Crystal Palace, and will know that three points will overtake Forest into the play-off places.
