Huddersfield Town are counting on a windfall from Cardiff City's move for QPR goalkeeper Alex Smithies.
The Huddersfield Examiner says Town included a sell-on clause when Smithies, now 28 and a promotion-winning Wembley hero in 2012, moved to Loftus Road in a near £2m deal in 2015.
Town would benefit from any profit made by QPR should the goalkeeper's proposed £3.5m package transfer to South Wales go through, although the exact percentage remains confidential.
QPR are expected to receive £3m guaranteed for the Town product, with another £500,000 should Cardiff stay in the Premier League next season.
Smithies has made 107 appearances for QPR, where he originally signed a three-year deal, having previously made 274 appearances for Town.
