Barnsley are also under threat from relegation but have pulled themselves out of the bottom three with their recent good form. Their 2-1 win over Wolverhampton Wanderers on Tuesday moved them two points ahead of the relegation zone.
Barnsley boss David Flitcroft may be without Kelvin Etuhu as the player continues to recover from a facial injury. Jacob Mellis could start after coming off the bench to net the winning goal against Wolves.
