Warnock hailed his team for their unstinting efforts in coming from behind to beat Middlesbrough 2-1 on Saturday, thanks to a brace from in-form striker Luciano Becchio.
"We put our bodies on the line near the end and there were a lot of tired legs out there," said Warnock.
One player who will be missing at the City Ground will be on-loan midfielder Michael Tonge. He played the full game against Boro in his final appearance before his return to parent club Stoke, although Leeds are hoping to make the deal permanent during the January transfer window.
Veteran Michael Brown, an unused substitute on Saturday, could be called upon to take Tonge's place in central midfield, while winger Aidy White is pressing for a start after coming on as a substitute at the start of the second half against Boro.
South African striker Davide Somma is also in contention after coming off the bench on Saturday for his first appearance since May 2011.
Fellow forward Becchio will continue to lead the line, with his two goals at the weekend taking his season's tally to 17 - just three short of his best-ever return for the club.
Midfielder Rudy Austin and defender Leigh Bromby remain long-term absentees.
