Leeds United defender Pascal Struijk has been ruled out for the rest of the season after undergoing groin surgery.
The 24-year-old Dutchman has not featured since picking up the injury in the 2-1 defeat at Preston on Boxing Day.
"It was a pretty long and complicated surgery but it went well. He's started rehab and he'll be back for pre-season," boss Daniel Farke said.
The Whites are top of the Championship with eight games of the season to go.
