Middlesbrough boss Gareth Southgate will be without Argentinian midfielder Julio Arca for the Coca-Cola Championship clash with Derby.

Arca will miss the game at the Riverside Stadium through suspension after picking up his fifth booking of the campaign in Saturday's 1-0 home defeat by Watford.

Defender Seb Hines will also be unavailable after suffering a knee injury in training.

Skipper Emanuel Pogatetz could play some part following his return from knee surgery to the 18 as an unused substitute at the weekend, while Rhys Williams has recovered from his international exertions with Australia.

But Chris Riggott and Andrew Taylor (both ankle), Caleb Folan (hamstring) and Matthew Bates (cruciate ligament) are still out.

Fredrik Stoor will miss the clash after becoming the latest player to join the Derby injury list.

The Swedish defender, on loan from Fulham, was helped off 14 minutes from the end of the goalless draw with Midlands rivals Leicester after sustaining an ankle injury.

Paul Connolly, his replacement at the Walkers Stadium on Saturday, will return to the starting line-up at right-back.

Lee Hendrie is also a doubt. The midfielder replaced Lee Croft after an hour at Leicester but was substituted himself soon afterwards because of a tight hamstring.

Boss Nigel Clough, whose list of absentees is already into double figures, said: "It was precautionary to take him off because we could not risk him doing more damage. If the hamstring had gone, he would be out four to six weeks and we couldn't afford that."

Kick-off at the Riverside Stadium is at 8pm.
