Cardiff City goalkeeper David Marshall is the subject of an approach from Premier League side Hull City, BBC Wales Sport has learned.
Saturday's Championship clash with Reading could be the Scottish international's farewell ahead of a potential £5m move.
Marshall, 31, has made more than 280 appearances for the club since arriving from Norwich City for free in 2009.
Cardiff have signed Bolton goalkeeper Ben Amos on a season-long loan.
However, they have also sold back-up stopper Simon Moore to Sheffield United.
Marshall, considered one of the top goalkeepers outside the Premier League, was the subject of interest from West Bromwich Albion last summer.
