Eight board members at O'Charley's on Monday resigned their positions as part of the process that has Fidelity National Financial paying more than $210 million to buy the local restaurant chain. Of the 11 directors in place last week, only three — Bill Andrews, Doug Benham and Phil Hickey — now remain. The other eight have been replaced by four FNF-appointed men, with Hickey turning over the chairman's seat to FNF CEO George Scanlon.
