Cousin and Folan lead Hull City exodus
The Tigers boss has been told the club need to trim around 9m from their annual wage bill to help tackle their financial problems.
Brown has said he will assess offers for any of his players on their merits but out-of-favour pair Folan and Cousin look set to be among the first to leave, possibly on loan.

Brown said: "There is interest for Daniel Cousin and Caleb Folan.
"Daniel Cousin is on African Nations duty and it is very difficult for him to come back and sign papers.
"Until that happens then there won't be a deal on the table, regardless of what anyone else says.

Brown pointed out, however, that Republic of Ireland international Folan has not handed in an official transfer request.
Two other players, Kevin Kilbane and Jan Vennegoor of Hesselink, have also been linked with loan moves this week.
Kilbane is reported to be interesting Wolves while Vennegoor of Hesselink is said to be a target for Middlesbrough.
