Andy King will be assessed ahead of Leicester’s trip to Crystal Palace after a sickness bug.
The midfielder missed the 1-0 win over Newcastle on Monday, which sent the Foxes five points clear at the top of the Barclays Premier League.
Matty James is close to a return following a cruciate knee ligament injury but will not be considered for selection yet as he regains match fitness.
Provisional squad: Schmeichel, Schwarzer, Chilwell, Fuchs, Morgan, Huth, Wasilewski, Amartey, Schlupp, Simpson, Kante, Drinkwater, King, Inler, Albrighton, Mahrez, Gray, Dyer, Ulloa, Okazaki, Vardy.
Crystal Palace manager Alan Pardew will make a late decision on Mile Jedinak’s fitness ahead of Saturday’s crunch game at home to league leaders Leicester.
Jedinak has a sore back and will be assessed but Connor Wickham is still out with an adductor injury and not expected to return until after the international break.
James McArthur (ankle) and Marouane Chamakh (hip) will also miss the match at Selhurst Park as Palace look for their first league win since December.
Provisional squad: Hennessey, McCarthy, Speroni, Ward, Kelly, Dann, Delaney, Hangeland, Mariappa, Souare, Lee, Jedinak, Ledley, Zaha, Puncheon, Bolasie, Cabaye, Mutch, Campbell, Adebayor, Sako, Gayle.
