Kebe missed the goalless draw with Leeds on Good Friday with a thigh injury and he will be assessed after his pace on the break was sorely missed at Elland Road.
Hal Robson-Kanu will start again if Kebe misses out as the Royals look to make it 14 games unbeaten.
Captain Matt Mills has returned to the heart of the defence after a month out with a groin injury and forward Noel Hunt is back after a foot injury.
Goalkeeper Adam Federici is back after nine games out with a knee injury but has been restricted to a place on the bench due to the form of England Under-21 international Alex McCarthy.
A win could take Brian McDermott`s side to within a point of second place.
