The Reds play 16th-placed Bournemouth at home on Saturday. The Cherries are four points above the relegation zone and not safe yet.
Swansea City (ahead of Forest on goal difference) are also at home but must face league leaders Southen United who need points themselves to be sure of promotion.
Barnsley (one point ahead) entertain Bradford at Oakwell. Colin Todd's side are 11th in the table and can neither make the play-offs or be relegated.
