Midfielder Prince Buaben has failed to agree personal terms with Scottish Premiership side Ross County.
According to Sky Sources, County have agreed a deal with Hearts for the services of the former Ghana international.
Buaben has made 60 league appearances for the Scottish Premiership side and has scored six goals from a central midfield position.
He spent four seasons at Dundee United before moving south of the border to Watford in the Championship, where he stayed until October 2013.
