England international Luke Young's proposed transfer from Charlton Athletic to Middlesbrough has moved a step nearer after the right-back passed a medical at the Riverside Stadium.
The two clubs agreed a transfer fee of £2.5million for the 28-year-old at the weekend.
"Luke has been through all the medicals, that was fine, it's really just a case of getting all the forms through from Charlton and were pretty much there," Boro boss Gareth Southgate told the club's official website.
"We're delighted with that one, but until it's all signed I don't want to say anything further."
Meanwhile, Southgate has once again dismissed rumours linking Yakubu with a move away from Teesside this summer.
Manchester City, Portsmouth and Birmingham City have all been linked with the Nigeria international, but Southgate insisted: "I've had a chat with him again today and he's very happy.
"We've had no contact from any other club and nor would we welcome any.
"As far as we're concerned he's our player, he's in training with us and he seems very settled."
Manchester United manager Sir Alex Ferguson also confirmed on Wednesday that Boro had expressed an interest in signing Alan Smith.
