Reading boss Brian McDermott is unlikely to make any changes.
The Royals moved into the play-off places on Saturday with a home win over Portsmouth and McDermott could name the same XI.
Full-back Andy Griffin was on the bench on Saturday after six games out with an Achilles injury but midfielder Brynjar Gunnarsson could continue to deputise.
Winger Jobi McAnuff returned from a hamstring injury and is fit while Australian goalkeeper Adam Federici is still missing as he recovers from a knee problem.
Striker Noel Hunt (foot) is out along with on-loan QPR midfielder Mikele Leigertwood (calf) and defender Matt Mills (groin).
Shane Long will continue as the lone striker after he reached the milestone of 50 goals for the club with a brace on Saturday.
Preston boss Phil Brown could again be without striker Chris Brown and defender Sean St Ledger.
Both men are nursing injuries which forced them to miss Saturday's 2-1 home win over Swansea and will be assessed.
On-loan Tottenham defender Bongani Khumalo took St Ledger's place in defence against the Swans, with Barry Nicholson replacing Brown and starting in an advanced midfield role behind Iain Hume.
North End boss Brown will be reluctant to make any changes after his side's impressive performance which lifted them off the foot of the table and secured a third straight win.
Brown said: "There was a 100% buy-in by everyone in the squad - the 11 who started, the three subs who came on and the four left on the bench."
