Hull are poised to make George Boateng their third summer signing after agreeing a deal with Middlesbrough for the midfielder.
Tigers boss Phil Brown revealed he will now attempt to agree personal terms with the 32-year-old, who has been looking for a new club since being told he could not be guaranteed first-team football at the Riverside.
Brown told BBC Radio Humberside: "The deal between ourselves and Middlesbrough has been agreed.
"It's now just a matter of fine-tuning the deal between us and George and that's a process that does take time."
Boateng cost Boro £5m from Aston Villa in 2002.
His agent Barry Silkman told BBC Sport: "He has a year left on his contract, but he's been there for five or six years and given them good service.
"He played about 80 per cent of the season, but he just thinks that maybe it is the right time to move on.
"Middlesbrough recognise he has been a great professional and say they won't hold out for a king's ransom should he wish to leave and won't stand in his way."
Boro boss Gareth Southgate confirmed on Monday: "George has expressed a desire to move on.
"He's having talks with a couple of other clubs and that is the decision he has got to make now."
Hull have already signing Geovanni on a free transfer and Craig Fagan for £750,000 as they prepare for their first season in the Barclays Premier League.Reuse content
