The Reds are set to be cheered on by 2,800 supporters
Nottingham Forest have received a further 300 tickets for Saturday’s game at Birmingham City.
The additional allocation will be the final one the Reds receive having already sold 2,500 tickets for the trip to St Andrew’s.
They must be purchased through the Forest ticket office and will cost £25 for adults and £20 for students and supporters aged over 65.
Fans aged 18 and younger can get in for £15, with tickets for those 13 and under costing £10.
The Reds will hope to break into the Championship’s top six with victory over a team who are struggling in the relegation zone.
City have won just once under their new manager, Steve Cotterill, and that came in his first game in charge, a 1-0 home success over Cardiff City, but have yet to taste victory in the four since, losing three and drawing just once.
They sit in the bottom three, a point adrift of safety with Bolton and Sunderland beneath them.
