The hosts have only won one of their last five matches but still sit level on points with Ipswich Town, who currently occupy the final playoff spot.
Brian McDermott's side fell to a 2-1 defeat at the hands of Nottingham Forest in their last outing but have only dropped four points from their last seven matches at Elland Road, winning five and drawing the last two.
Blackburn will also have one eye on a playoff charge in the second half of the season having lost just one of their last five games to rise to 12th in the table.
They could close the gap to the top six to just one point if results go their way on New Year's Day, but they will have to overcome their poor away form that has seen them win just twice on their travels all season.
Possible starting lineups
Leeds: Kenny; Pearce, Lees, Zaliukas; Peltier, Murphy, Brown, Austin, Pugh; Smith, McCormack
Blackburn: Eastwood; Henley, Hanley, Dann, Spurr; Taylor, Lowe, Dunn, Marshall; Cairney; Rhodes
