The Bombers announce that Kyle Hardingham, Sean Gregory and Johnny Rayner will not be offered new contracts for next season, while small forward Leroy Jetta recently told the club that he wanted to explore his options via free agency.

"The club would like to thank all four men for their contribution and dedication during their time at Essendon," general manager of football operations Robb Kerr said.

"On behalf of everyone at the club we wish them every success in the future, both on and off the field."
