Vydra, HRK and Williams are all doubts (hamstrings). Of the three HRK is most likely to play but late fitness tests will decide finally.
Aaron Tshibola definitely out having had surgery last week and it is not known when he will return.
TEAM NEWS BURNLEY
Burnley are without midfielder Dean Marney and long term absentees Ashley Barnes & Lukas Jutkiewicz.
Their new signing from Brentford, James Tarkowski, is ready but has not been able to dislodge Michael Keane or Ben Mee from the centre of defence.
Unfortunately both Vokes and Gray are available not to mention George Boyd

(UN)LIKELY LINE-UPS
Reading
Al-Habsi, Gunter, Cooper, McShane, Obita, Norwood, John, Robson-Kanu, Quinn, Piazon, Kermorgant.
Burnley
Heaton, Lowton, Keane, Arfield, Mee, Jones, Barton, Ward, Boyd, Vokes, Gray.
THE REFEREE
Nottinghamshire's James Adcock
He's given 52 yellows so far this season but no reds in 20 previous games.
His previous Championship appointment was Sheffield Wednesday's 2-1 win at Birmingham City last Saturday.
Our history with Mr Adcock
28 Sep 2013 > Reading 2-0 Birmingham City
22 Apr 2014 > Reading 2-0 Middlesbrough
28 Sep 2014 > Reading 3-3 Wolverhampton Wanderers
24 Feb 2015 > Huddersfield Town 3-0 Reading
Outcome?
To be honest given the disjointed crap we're currently throwing up (literally) in the league a draw would be a good result.
