Middlesbrough midfielder Barry Robson has a chance of returning to action in the clash with Bristol City.
Recent signing Robson has missed the last two games with a hamstring problem, but manager Gordon Strachan is hoping he could be back for the weekend.
However, he expects once again to be without a host of players with Chris Riggott (hamstring), Jeremie Aliadiere (ankle) and Rhys Williams (pelvic injury) all doubts and Isaiah Osbourne still struggling with the knock which has kept him out recently.
Emanuel Pogatetz has returned to light training after his own hamstring problem, but still has some way to go, while Matthew Bates (cruciate ligament) and Seb Hines (ankle and knee ligament) remain sidelined.
Youngster Joe Bennett's name was added to the casualty list in midweek when a foot injury suffered on reserve team duty left him on crutches.
Bristol City manager Gary Johnson could ring the changes after their humiliating defeat against Cardiff.
The Robins were thrashed 6-0 at Ashton Gate by Dave Jones' ruthless Bluebirds on Tuesday night and Johnson's side have won just one of their last six Coca-Cola Championship matches.
Lewin Nyatanga could be recalled to the City defence, while midfielders Evander Sno, Marvin Elliott and Ivan Sproule are all pushing for recalls to the starting line-up.
Recent signings Patrick Agyemang and Jamal Campbell-Ryce will be looking to erase the memories of their Robins debuts and both players should keep their places in the side.
Johnson has no injuries or suspensions to contend with as he looks to get his side's play-off push back on track.
