Goalkeeper Mark Schwarzer remains doubtful with the back problem which prevented him from playing in the draws with Bolton and Manchester United. Long-term injury victims Philippe Senderos (Achilles), Andrew Johnson (knee) and Diomansy Kamara (foot) are out.
Port Vale boss Micky Adams is unlikely to make changes. Vale won 3-1 at Southend on Saturday and Adams is likely to stick with the same squad for the trip to Craven Cottage.
Striker Marc Richards looks set to start after scoring twice at Roots Hall to seal Vale's third consecutive away win of the season. Kris Taylor and Tommy Fraser are likely to keep their places on the bench.
Doug Loft is ruled out with two broken ribs and a punctured lung which he sustained during the 1-1 league draw with Chesterfield. The midfielder is the only injury concern.
