Brian McDermott has revealed that Mikele Leigertwood and Jimmy Kebe could be doubts for this evening's cup tie with Manchester United.
Both are battling to recover from knocks, whilst the Royals will also be without Hope Akpan and Nick Blackman - both of whom are cup-tied after joining in January.
"Alex McCarthy is coming back pretty well but won't be ready yet, Jason Roberts isn't ready," said McDermott.
"Mikele Leigertwood has a bit of a knock - we'll have to wait on him. Jimmy Kebe has a bit of a knock, we'll have to wait on him too."
There is more positive news concerning Danny Guthrie, who will travel to Old Trafford after missing the training camp in Dubai.
"Danny stayed behind last week to look after his wife, who is seven and a half months pregnant, but he trained with us over the weekend and will travel up to Manchester United."
