New signing Barry Robson is a major doubt for Middlesbrough's Championship clash with Swansea.

The 31-year-old, who made his debut at Sheffield United last weekend, is struggling with a hamstring injury.

Loan signing Isaiah Osbourne is battling to shake off an unspecified knock and Jeremie Aliadiere is nursing an ankle injury.

Striker Leroy Lita has completed his three-match ban after being sent off against Scunthorpe on Boxing Day while Julio Arca and Gary O'Neil are expected to shake off bumps and bruises.

However, Emanuel Pogatetz (hamstring), Rhys Williams (pelvis), Andrew Taylor (hernia surgery), Seb Hines (ankle and medial ligament) and Matthew Bates (cruciate ligament) remain on the sidelines.

Swansea manager Paulo Sousa is boosted by the news that Cedric van der Gun will be available.

The Dutch winger had been struggling with a hamstring problem and missed the Swans 1-0 victory over Leicester last weekend.

However, defender Albert Serran is expected to be out of action for at least eight weeks with a hamstring injury.

The Spaniard left the field before the end of Saturday's win over the Foxes despite only entering the fray as a 73rd-minute substitute.

Wales captain Ashley Williams was dropped for the clash against Nigel Pearson's side but will battle it out with Federico Bessone for a first team berth.

Striker Craig Beattie is expected to be added to the starting line-up following his 78th-minute appearance from the substitutes bench against the Foxes following illness and a knee injury.
