Exiting defender David Wright is interesting newly-promoted Leeds United and League One Charlton Athletic. The Addicks are also understood to be considering a move for their former striker Kevin Lisbie, having previously been linked with Richard Wright.
Both Wrights were released at the end of the season, while Lisbie has another year left on his Town contract.
Lisbie is also likely to be targeted by his other former club Colchester United, with whom he spent 2009/10 on loan, while Millwall, who announced that Town midfielder Liam Trotter had agreed to join them earlier this afternoon, have previously expressed an interest in the 32-year-old.
