Speaking to the Official Club Website, former Everton boss Royle said: "Darren Bent and Georges both trained fully today and will be in contention for the trip to Highfield Road.
"We expected Georges to be out for a couple of weeks initially but he has recovered quickly and we are delighted to have him available, especially with Johnny Mac out."
The other two doubts, Tommy Miller and Chris Bart-Williams, have also resumed training and are expected to be named in Royle's squad for Highfield Road tommorow.
