Burnley boss Brian Laws is optimistic that Martin Paterson and Chris Eagles will be passed fit for the game.
Paterson has not played since the 1-1 draw at home to Doncaster on November 9 due to a thigh strain and will be assessed.
Eagles was absent from Burnley's last game against Derby a fortnight ago because of a niggling back problem but he too has a chance of being passed fit.
Left-back Danny Fox is still recovering from strained ankle ligaments but could possibly make his comeback at Cardiff on December 18.
Laws said: "Danny is on track. He has made very good progress. We are very hopeful that he will be able to be involved in the Cardiff away game."
Leeds manager Simon Grayson has Paul Connolly available for the trip.
The defender missed last weekend's 2-1 win over Crystal Palace through suspension after picking up five bookings for the season and Grayson will have to decide whether to recall him or keep Andy Hughes in defence.
Bradley Johnson, who entered a war of words with chairman Ken Bates this week due to contract issues, has started the last three games for the Whites since being placed on the transfer list and is likely to keep his place in midfield despite calls for him to be dropped to the bench.
Defender Richard Naylor is still recovering from minor knee surgery while strikers Ross McCormack and Billy Paynter are both pushing for starting places as Leeds look to extend their unbeaten run to eight games.
