Hull City 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 £5million from Aston Villa in 2002.
His agent Barry Silkman said: '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% 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.'
• Meanwhile, Middlesbrough have tied up the futures of three of their young prospects.
Defender Tony McMahon and striker Tom Craddock, both 21, have signed one-year deals with the club.
FA Youth Cup winning captain McMahon made his senior debut as a teenager back in 2004, but has been plagued by injuries since and has just 25 senior appearances to his name.
Craddock made his maiden first-team appearance on the final day of the 2005-06 season, when then-manager Steve McClaren fielded a squad which included 15 locally-born players.
He has made played in four more senior games for the club since and has had loan spells at Wrexham and Hartlepool.
Meanwhile, 18-year-old scholar Joe Bennett has signed his first professional contract with the club.
