Reading will be without captain Matt Mills, who begins a four-match ban after an appeal against his sending off against Ipswich was rejected.
Gylfi Sigurdsson is expected to return after being rested for that game.
MATCH PREVIEW
Cardiff, who have won three of their last four matches and are unbeaten in seven, are close to sealing a play-off place and will face teams in the bottom half of the table in their final three league games.
Before that, they face a Reading side that could yet land a top-six place themselves after a stunning turnaround since manager Brian McDermott inherited a team that were struggling near the bottom of the table.
The Royals have won 10 of their last 14 league matches are now nine points outside the play-off places, with two games in hand on the teams around them.
Reading have won 15 and lost 15 of their league matches this season. They have also scored 55 goals, conceded 55, and collected 55 points.
