Watford will be without midfielder John Eustace for the visit of Reading.
Former Stoke man Eustace is banned after picking up five yellow cards this season so manager Malky Mackay will be forced into at least one change from the side which went down 3-2 at Burnley last week.
Youngster Ross Jenkins could come into the side in Eustace's place or Josh Walker may make his first start since joining from Middlesbrough.
Eustace was credited with the infamous 'ghost goal' when the two sides met in 2008 when referee Stuart Attwell awarded the Royals a goal when Eustace headed a corner wide of the post.
Winger Don Cowie returned from a knee injury to score at Burnley last weekend to leave Mackay with no injury worries.
Troy Deeney will hope to get the nod to continue to partner Danny Graham in attack despite the former Walsall man scoring just once all season.
Reading could welcome back winger Jimmy Kebe for the trip to Watford.
The Mali winger has missed the last five matches with a knee injury but is close to a comeback and could feature for Brian McDermott's men at Vicarage Road.
However, striker Noel Hunt has been in excellent form in Kebe's wide role in recent games and might keep his place in the starting XI.
Central midfielder Brynjar Gunnarsson has still got a thigh problem and will miss out as the Royals look to keep pace with the play-off pack.
Club captain Ivar Ingimarsson has suffered a minor setback in his recovery from a hamstring problem and remains on the sidelines having not played since March.
Young full-back Julian Kelly is still out with his hamstring injury but he would not be involved anyway.
