Hull manager Phil Brown claims a deal for Wigan striker Marlon King is 'almost 90% done'.
The 28-year-old Jamaica international discussed personal terms with the Premier League newcomers yesterday.
King only joined Wigan in January but boss Steve Bruce seems prepared to cut his losses on the player after just one goal in 15 appearances following his £4million move from Watford.
Brown told Sky Sports News: 'I spoke at length with Marlon and his representatives yesterday at the training ground.
'We have agreed our end. Where Wigan are concerned, they are happy with the transfer dealings, and we are happy with the contract negotiations with regards to Marlon.
'But there are still loose ends to tie up at the Wigan end, so we are just sitting back and waiting for the green light from Wigan. It is almost 90% done but that last 10% can always be the sticking point.
'There is still a medical to go through for a start.'
King is likely to cost a club record fee, beating the amount paid for Peter Halmosi earlier this month, which although undisclosed is thought to be around £2million.
Brown has signed five other players this summer as he prepares for the club's first season in the top flight in Craig Fagan, Geovanni, Bernard Mendy, George Boateng and Tony Warner.
That has made him one of the busiest managers in the Premier League but he insists he is not finished.
'We are nudging things along,' Brown added. 'We have got four or five bids on the table for players. It is no hidden secret we are after a centre-half or two, a striker or two, to bolster the squad.
'It's not that we are not going to give the current playing squad a chance to play Premier League football, but we understand we have to strengthen and improve the squad.'
