Leeds midfielder Adam Forshaw will miss the rest of the season after fracturing a knee cap in training.
It will take the 30-year-old midfielder six weeks to recover, and Leeds' last game of the season is at his former club Brentford on 22 May.
Fit-again England midfielder Kalvin Phillips will return to the starting line-up at Crystal Palace on Monday.
"It's painful for us because he (Forshaw) is important," said Leeds boss Jesse Marsch.
"The main thing is that Adam is one of the guys who gives more to the group and does everything he can to think about the team first.
"He'll still be around and will still be a big part of the group.
"It should be a relatively straightforward recovery, so by the summer he should be ready to go."
