Luis Boa Morte's agent has claimed the West Ham midfielder has not been made aware of any interest in him from Hull.
Both clubs last week dismissed reports they had agreed a fee for the former Arsenal, Southampton and Fulham player but Hull boss Phil Brown has since admitted he is keen on recruiting the 31-year-old.
Amadeu Paixao, the former Portugal international's agent, said: "We have read in the newspapers that Hull are interested but we don't know anything about it. This club we do not know. Nobody has contacted us to allow Hull to talk to us, nothing has been said to us."
The Hammers are thought to be keen to offload some of their fringe players to reduce both the wage bill and, for practical reasons, the size of Gianfranco Zola's squad.
Boa Morte, who moved to Upton Park in a £5million move from Fulham in summer 2007, has struggled to earn a regular starting place during his time at the club.
It remains to be seen, however, how the recent departures of Matthew Etherington and Lee Bower - to Stoke and Birmingham respectively, the latter on loan - affect his status.
Paixao added: "He has never mentioned that he wants to leave West Ham. He has a house near the training ground, a wife and two kids. He is very happy there."
