Middlesbrough will be without Jonathan Woodgate for Tuesday's FA Cup fourth round replay with Bristol City after the England defender suffered a hamstring strain.
The on-loan Real Madrid centre-half missed Saturday's 3-0 defeat at Chelsea and won't be risked by Boro boss Gareth Southgate for the visit of the League One side to the Riverside.
Abel Xavier and Emanuel Pogatetz look set to continue at the heart of the defence in the absence of the former Leeds United and Newcastle stopper.
"I think Woody will be all right by the weekend, but it's not worth taking a risk with his fitness," revealed Southgate.
"I don't want to try to rush him back and then find he misses the next five or six games."
Meanwhile, Southgate has vowed to give respect to Boro's lower league opposition after the 2-2 draw at Ashton Gate in the first meeting of the sides last month.
He added: "Obviously Bristol City haven't had the best of results since we played them but they are involved in other cup matches and it is a hectic time for them.
"Any side of Gary Johnson's is going to be difficult to play against and we will give them the greatest of respect again.
"This is a no lose game for them and so we have to respect them and prepare for another tough game.
"But we have home advantage and it's a game we should expect to win. We have to do everything it takes to make sure we do win."
