Leandro Bacuna could face familiar opponents on his Reading debut against former club Aston Villa on Tuesday night.
The defender or midfielder joined the Royals on Sunday on a four-year deal from Villa and there is no gentleman's agreement to prevent him playing against his former club so long as the paperwork is completed in time.
Midfielder Garath McCleary and Roy Beerens could be back in the squad after returning to first-team training.
Jon Dadi Bodvarsson, Jordan Obita. Yann Kermorgant, Tennai Watson and Callum Harriott remain out.
Ahmed Elmohamady is out for Aston Villa after suffering a mouth injury - which could need surgery - against Cardiff.
The 29-year-old was forced off just half-an-hour into Saturday's 3-0 defeat following a collision with Bluebirds keeper Neil Etheridge.
He adds to Villa's injury list which already includes Jonathan Kodjia, still out with a broken ankle he suffered at the end of last season.
Midfielder Mile Jedinak is also a week away from being available after undergoing groin surgery during the summer, while Jack Grealish has been ruled out for three months with kidney damage and Andre Green (groin) will be assessed.
