Randolph set for Addicks start

Rob Elliot is out for six weeks with the adductor muscle injury he suffered a fortnight ago and loanee Carl Ikeme, who made his debut at Carlisle last week, has been denied permission to play by Wolves.
Right-back Frazer Richardson will miss out again with a thigh injury so Elliot Omozusi keeps his place.
Midfielder Dean Sinclair (knee) and striker Leon McKenzie (thigh) are the only other injury absentees.
On-loan Reading winger Dave Mooney is also unable to play in the competition so youngster Tamer Tuna could make the bench.
Scott Wagstaff will be hoping to play against the side for whom he made five appearances on loan last season.
The match kicks off at 1.30pm.
