Whites head coach Marcelo Bielsa still has his fair share of injuries to contend with and the Leeds boss provided his latest team news at Friday morning's pre-match press conference.
What is certain is that Patrick Bamford, Luke Ayling and Robin Koch are all still out.
Leeds left it late to bag a 1-1 draw at home to Wolves in their most recent league assignment last Saturday as bottom of the table Norwich were thumped 7-0 at Chelsea.
The newly-promoted Canaries have amassed just two points from nine games played and sit five points and three places behind fourth-bottom Leeds.
After Bielsa provided the latest news on the injuries front, this is how we expect Leeds to line up in Sunday's 2pm kick-off at Carrow Road.
7. CM - Stuart Dallas
Much depends whether Firpo starts at left back. If he does, the admirable Dallas who is bravely battling on following the death of a close friend will likely move into centre midfield although Mateusz Klich, Adam Forshaw and Shackleton are alternatives.
8. RW - Raphinha
The Brazilian star seems to have dodged a major bullet despite hobbling off after a poor late challenge by Romain Saiss against Wolves. Likely to be available says Bielsa and the classy Brazil international clearly starts if fit enough.
9. LW - Dan James
If Raphinha starts then it's one of Dan James or Jack Harrison for the other wing slot, despite Crysencio Summerville's quick climb up the ranks. Harrison was taken off at half-time against Wolves and James would be the likely call.
10. ACM - Rodrigo
United's record signing turned on the style in the second half against Wolves and linked up really well with teen star Joe Gelhardt following his introduction from the bench. Rodrigo clearly starts, but who partners him with Patrick Bamford still out?
11. ST - Joe Gelhardt
Gelhardt was brilliant off the bench last weekend and despite his tender years must be close to starting, especially with Bamford out. Bielsa started Dan James upfront against Wolves and Tyler Roberts or Rodrigo as 9 are other options but 'Joffy' could already be the one.
