Ian Holloway has begun his summer clearout at Millwall by releasing four players from the club.
Shane Lowry, Andy Keogh, Liam Feeney and Jack Smith - all of whom were out of contract - have parted company with the Lions, while Jermaine Easter has signed a new one-year contract.
A statement on Millwall's official website read: "The club would like to place on record its thanks and gratitude to the quartet for their efforts whilst at The Den, and wish them all the best for their future careers."
Holloway guided Millwall to safety on the final day of the Championship season last weekend.
