Michael Turner and Javier Garrido both picked up injuries against Stoke and are doubtful, while Russell Martin could also remain sidelined with an ongoing back problem.
Garrido is perhaps most likely to feature of the trio, with Steven Whittaker continuing at right-back after making his own comeback from injury last weekend.
Ryan Bennett may well replace Turner at the back, but elsewhere the team is likely to remain unchanged from the XI that picked up a win over Stoke last time out.
Reading are still yet to win in the Premier League and will feel that a home game against a direct rival in the relegation battle will be the best way to get off the mark and close the gap emerging above them.
Norwich are unbeaten in three games, however, and Chris Hughton will want to continue the momentum to see them push further up the table and away from the drop zone.
Both sides will really want to win this game, with a draw not really helpful to either, so it should be an entertaining and end-to-end spectacle with little to choose between the two sides.
