Wolves manager boss Mick McCarthy has released four players and made another four available for transfer.
Striker Carl Cort, midfielder Rohan Ricketts and goalkeeper Michael Oakes are now free agents.
And striker Craig Davies is also leaving as his season-long loan spell from Verona has come to an end.
Denes Rosa, Jamie Clapham, Jemal Johnson and Tomasz Frankowski have been placed on the transfer list as McCarthy prepares to freshen up his squad.
McCarthy said: "I want to bring new players in - no question about that.
"So I told all the lads before they left yesterday that some will be leaving and some will come in. That's the way it is."
