Leeds United boss Neil Warnock has revealed that Tom Lees and Steve Morison both suffered injuries in the 1-1 draw with Peterborough United on Tuesday.
Lees picked up a hip problem in the Championship clash, while Morison also had to depart the field with a calf strain.
"It was like battle stations in the dressing room afterwards. Tom Lees and Steve Morison will both have precautionary scans so we'll see where are with them," Warnock told the club's official website.
"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."
Leeds currently sit 10th in the Championship table.
