Reading will have a fully-fit squad to choose from as they bid to record back-to-back home victories.
Several Royals players, including Adam Federici, Mikele Leigertwood and Hal Robson-Kanu returned from international duty unscathed.
Simon Church missed Wales' 4-1 win over Norway with a knock while Jem Karacan (ankle) withdrew from the Turkey Under-23 squad.
But the duo have returned to training and will be available to manager Brian McDermott.
Meanwhile winger Jimmy Kebe, who announced he excepts to leave the club in January or over the summer, will hope to keep Robson-Kanu out of the starting line-up again.
McDermott's side entered the international break on a high after beating Birmingham 1-0 at the Madejski Stadium.
Goalkeeper David Marshall is set to return to Cardiff's starting XI.
The Bluebirds stopper came off at half-time in the 3-0 victory over Derby due to illness and the 26-year-old did not feature against Crystal Palace.
But he looks set to return in place of Tom Heaton as Malky Mackay's side aim to extend their unbeaten run to six matches.
Midfielder Stephen McPhail could also return to the squad after missing out against the Eagles for personal reasons.
The only absentee for Mackay will be striker Rudy Gestede, who has a hamstring strain.
Welsh central defender Darcy Blake may have to make do with a place on the bench once more despite featuring regularly for his country.
