Kilgallon, 19, is now poised for his first Barclaycard Premiership start after making just four substitute appearances to date, with his debut more than 13 months ago.
Villa boss David O'Leary has to decide whether to persevere with Stefan Moore in preference to Darius Vassell.
Dion Dublin's fine form as a defender may again mean Ronny Johnsen on the substitute's bench.
Leeds (from): Robinson, Kelly, Harte, Matteo, Morris, Camara, Barmby, Bridges, Viduka, Pennant, Chapuis, Johnson, Duberry, Batty, Olembe, McPhail, Lennon, Milner, Sakho, Kilgallon, Richardson, Carson.
Aston Villa (from): Sorensen, Delaney, Mellberg, Dublin, Samuel, Hendrie, McCann, Whittingham, Barry, Angel, Moore, Vassell, De la Cruz, Hitzlsperger, Johnsen, Postma, Ridgewell.
Leeds are advising supporters attending the game against Aston Villa to get to the ground early.
There will be no Leeds First buses to Elland Road, nor will there be any GNER or Midland Mainline rail services, so the car parks are expected to be extremely busy.
Demand for match tickets has been high.
