Hull have accepted an undisclosed offer for defender Sam Ricketts from another Premier League club.
The Tigers have revealed few details of the approach for the Wales international but have confirmed the 27-year-old has been given permission to speak with the interested party.
Manager Phil Brown told BBC Radio Humberside: "We've accepted an offer from a Premier League club and it gets up to our evaluation of Sam. We have allowed him to go and talk to this club."
Ricketts made 35 appearances for the Tigers last season, mostly in the full-back positions. Brown claims he does not especially want to sell the player but had challenged him to earn a new contract with his current deal due to expire at the end of the season.
He said: "I don't particularly want to get rid, I said I wanted a little more consistency in performance. It was provided towards the end, the last couple of games, but I need that for 38 games from whoever - it doesn't matter if it is Sam Ricketts or whoever.
"I put that to Sam in his appraisal at the start of the season, 'Give me 10 games and if we get the consistency we got at the end of the season there will be a contract on the table'."
Hull are now hoping for a positive response from their latest target, Bobby Zamora, after meeting with the £5million-rated Fulham forward this week.
Brown said: "We have put a contract on the table, a very lucrative contract in terms of what we think of Bobby Zamora.
"We are standing firm on it, this is our evaluation of Bobby Zamora, end of story. The opposition always begs to differ. We are in that no man's land again, awaiting a response.
"I have not put a timescale on it. We're giving him time to think about it, it will probably be in the next 24 hours."
