Javi Gracia admits relegation-threatened Leeds United have a 'big problem' and he is 'worried' after suffering a triple injury blow.
The Whites boss says midfielder Tyler Adams faces a fight to be fit again this season having been forced to have an operation on his hamstring.
Gracia also ruled defender Max Wober and forward Willy Gnonto out of Saturday's game at league leaders Arsenal with the respective hamstring and ankle injuries they picked up on international duty.
The duo are now major doubts for next week's home clashes with relegation rivals Nottingham Forest and Crystal Palace.
