The pressure mounted on Leeds' American coach, Jesse Marsch, after his team fell to a fourth straight defeat in the Premier League with a 3-2 loss at home to Fulham on Sunday.
The final whistle at Elland Road was greeted with boos, with Leeds now winless in the league since Aug. 21 - a run of eight games - and also in the relegation zone.
The hosts failed to hold onto a lead given to them by Rodrigo in the 20th minute.
Goals by Aleksandar Mitrovic, Bobby De Cordova-Reid and Willian put Fulham 3-1 ahead before Crysencio Summerville's stoppage-time consolation.
There were chants against Marsch and the club's board in the final minutes of the game.
