Boro without Harrison

The striker, who scored just three minutes after coming on as a substitute in the 3-0 midweek win over Rotherham, is cup-tied having already played in this season's competition for Carshalton Town.

Midfielder Stacy Long and striker Yemi Odubade are again doubtful after missing out against the Millers with calf and back injuries respectively, while midfield duo Darren Murphy and Joel Byrom are still sidelined with shoulder and foot/ankle problems respectively.

Boro will be hoping to cause another FA Cup upset after dumping Premier League side Newcastle out at the third round stage.
