Burnley have released David Edgar, Brian Stock, Keith Treacy and Nick Liversedge - with the club indicating they would like out of contract Michael Duff, Junior Stanislas and Danny Lafferty to stay.
Treacy has not been offered terms at the end of his three-year contract, but it is understood that the former Republic of Ireland international winger will be given the chance to impress upon the return to pre-season.
Edgar, Stock and Liversedge have been told they are free to leave Turf Moor at the end of their current contracts, which expire this summer.
Canadian international Edgar made 114 appearances for the club after joining from Newcastle United in 2009, scoring four goals.
The 26-year-old made his last appearance in the vital 1-0 win at Blackpool in mid-April.
Midfielder Stock spent two-seasons at Turf Moor after being signed by former Bournemouth teammate Eddie Howe from Doncaster Rovers.
The 32-year-old went on to make a total of 42 appearances; his last coming as a substitute in the crucial 1-1 draw at Watford en-route to promotion to the Premier League.
Treacy joined Burnley in the summer of 2011 from Lancashire neighbours Preston North End.
Treacy, who had a loan spell at Sheffield Wednesday in 2012, made 75 appearances for the Clarets, scoring five times.
Goalkeeper Liversedge spent just one-year at Turf Moor after joining from non-league Whitby Town, but did not make a first team appearance.
