On-loan defender Steven Caulker has responded well to treatment on a hip injury and could yet be included in Bristol City's squad.Captain Louis Carey is back in contention after two months on the sidelines, but Christian Ribeiro (hamstring) is a doubt.
Boro are hoping Marvin Emnes (foot), Barry Robson (thigh) and Jason Steele (knee) will be available.
But midfielder Nicky Bailey is a major doubt after going down with a virus.
MATCH PREVIEW
Bristol City and Middlesbrough come into this game in identical form, with both sides having won two, drawn two and lost two of their last six league matches.
Boro are two places above the drop zone and three below City, who are unbeaten in eight home league games and have been making decent progress under boss Keith Millen. A win on Saturday would take them eight points clear of the Teessiders.
Tony Mowbray's side, who have drawn their last two league games, have struggled to score away from home this season. They have scored only nine Championship goals on their travels - fewer than any other team.
That will give Boro striker Leroy Lita even greater incentive to perform well against his former club. Lita was an England Under-21 international during his time at City, and scored 38 goals for the club before leaving in 2005.
