Winger Kebe has been one of the Royals' most instrumental players this season but missed the FA Cup win at Stevenage at the weekend through illness. He is being monitored and could return in Wales.
Central defender Alex Pearce also missed out at the weekend with a thigh injury and is likely to be unavailable again, meaning club captain Ivar Ingimarsson will continue after his recovery from a long-term hamstring problem.
January signings Mathieu Manset, Brett Williams and Sean Morrison could all travel and be included for the first time.
Strikers Manset and Williams arrived from Hereford and Eastleigh respectively while centre-half Morrison has come in from Swindon. The trio were all cup-tied for the Stevenage game but could feature.
