Kenny Jackett’s side are three points behind Ipswich, who occupy the final play-off spot in the Sky Bet Championship.
Their 2-1 defeat at Middlesbrough on Tuesday handed the initiative to the visitors, managed by ex-Molineux boss Mick McCarthy, in the race for sixth.
Tommy Rowe is back in training after a knee injury but is unlikely to be included in the squad after a lengthy lay-off.
Ipswich manager McCarthy also has no new injury problems but will still be without striker Luke Varney.
Varney sustained a hamstring injury in the recent home victory over Blackpool and missed the midweek win against Cardiff.
David McGoldrick (thigh), Noel Hunt (knee) and Luke Hyam (knee) all remain sidelined.
Darren Ambrose (hamstring) and fellow midfielder Kevin Bru (calf) have both returned to training but are not yet ready for match action.
