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.
