Middlesbrough have decided not to appeal against David Wheater's controversial red card in Saturday's 2-1 defeat at Hull City.
The young defender was dismissed in the closing stages of the game after tussling with the Tigers' Brazilian star Geovanni.
The referee awarded Hull a penalty from which Marlon King netted and opted to send Wheater, who will now serve a one-match ban, off.
After the defeat Boro boss Gareth Southgate had been upset with the decision, saying: "It looks like a very soft penalty and it looks to me like it was offside when the ball was played.
"However, we should have got on with it and been goal-side once it's not been given.
"It also looks as though it was a very harsh sending-off. He's going away from the goal and was going wide.
"However, it's pointless getting involved in what the referee does. We can't be distracted by that. We've lost and we've got to take it."
