Millwall have confirmed on their official website that defender Alan Dunne won't be offered a new contract to stay at the club.
The likes of Danny Shittu, Ricardo Fuller and Richard Chaplow have been allowed to leave the club at the end of their contracts, with Millwall announcing their retained list earlier today.
Yet the biggest departure came in the shape of captain Dunne, who has played for the club for the whole of his career so far.
Dunne, 32, started his career with the Lions all the way back in 1990, and has racked up well over 300 league appearances for the club since arriving from Ireland.
Now though, with his contract expiring this summer, Millwall have taken the decision to let him leave for pastures new - and he could find himself at Celtic next season.
According to the Daily Mail, Celtic are hoping to land Dunne on a free transfer this summer, with the versatile Irishman reportedly on Ronny Deila's radar.
Able to play at right back, centre back and in midfield, Dunne can feature in a number of positions - something which may be appealing to Deila, especially now he's available for free after his release today.
