Tom Lees (Hip problem) and Steve Morison (Calf complaint) will undergo scans on injuries following Leeds' 1-1 home draw against Peterborough.
Both players had to come off on Tuesday night while striker Ross McCormack will also be examined after suffering a knock on the head during the Championship clash at Elland Road.
All three players are concerns ahead of the visit of West Yorkshire rivals Huddersfield for Saturday's derby.
"It was like battle stations in the dressing room afterwards," United manager Neil Warnock told the club's official website, probably meaning ‘military triage’ rather than ‘battle stations’, but hey, that’s why he’s a seven-time promotion-achieving manager and not a Pulitzer winner.
Warnock continued: "Tom Lees and Steve Morison will both have precautionary scans so we'll see where are with them.
"Ross took a bang and couldn't remember the second half so we'll look at him as well.
"There were a few others who took knocks and bumps as well so we'll have to see where are.
"We'll have a team out on Saturday and be strong, and the lads who play will stand up and not shirk anything."
I wouldn't be too sure about that considering our lack of quality depth in the squad. Most if not all Leeds fans (At least those who still want a play-off place) will be wishing the trio a full recovery in time for Saturday.
