Whites head coach Marcelo Bielsa had already gone over details of eight separate injuries approaching Sunday afternoon's third round FA Cup clash at West Ham United in which Leeds fell to a 2-0 defeat.
But the injury list has now been added to further ahead of this weekend's rematch against the Hammers at the London Stadium but this time in the Premier League.
On top of the injuries, Leeds also have suspensions to contend with and here is a full list of who is currently out with what and what has been said about when they are expected back.
7. Tyler Roberts (calf)
Roberts picked up a calf injury in the new year victory at home to Burnley and was forced off in the 58th minute, replaced by Joe Gelhardt who is also now injured. Bielsa said last week that Roberts would be out for around three more weeks.
8. Joe Gelhardt (ankle)
Teen striker Gelhardt again dazzled off the bench against Burnley but the forward then injured his ankle in training on January 6. Bielsa said at his pre-West Ham press conference that the teen would be absent for three weeks.
9. Patrick Bamford (below hip)
Bamford was set to start Sunday's cup clash at West Ham having recovered from his hamstring injury but missed out after picking up what Bielsa said was an injury below his hip in training that Bielsa described as not unidentifiable but not a muscular issue.
10. Junior Firpo (head)
Firpo collided with Illan Meslier in the first-half of Sunday's defeat at West Ham and came off in the second half. He did, though, take to social media afterwards to say he had felt a bit dizzy but was now well, although there are concussion protocols that must be followed.
11. Sam Greenwood (unknown)
Greenwood has become the latest player to be added to the list, the 19-year-old forward playing the first half of Sunday's clash at West Ham but then revealing on social media that he was gutted to have picked up an injury but that he will be back stronger.
12. Diego Llorente (suspended)
Llorente has started United's last two games after returning from a positive coronavirus test but picked up a fifth booking of the season against Burnley and must serve a one-game ban for this weekend's Hammers clash. Roberts is also banned but injured anyway.
