Fulham full-back Jazz Richards has been ruled out for two weeks with a calf injury.
The Wales international was taken off after just 37 minutes of the Whites' dramatic game with Reading last weekend and will miss the trip to Bristol City on Saturday.
Richards is also likely to be ruled out for the games with Burnley and Birmingham City but should return after the international break.
Jamie O'Hara is available to play against Bristol City after serving a one-match suspension, but goalkeeper Marcus Bettinelli and defender Jack Grimmer remain sidelined.
