Defender Pascal Struijk will serve a three-match ban after Leeds United lost their appeal against his red card during the defeat against Liverpool.
Struijk was dismissed for a challenge on Harvey Elliott that left the Reds midfielder with a dislocated ankle.
Elliott, 18, had surgery on Tuesday but could play again this season.
Struijk, 22, will miss games against Newcastle United and West Ham United in the Premier League and Fulham in the Carabao Cup.
He will be available again for the league game against Watford at Elland Road on 2 October.
