Shane Lowry axed by Millwall
Lowry, 24, had been at Millwall since joining on loan from Aston Villa in 2011 before his move was made permanent in January of 2012.
The left-back was a prominent figure for Millwall in the 2012-13 season, starting over 40 games and helping the club to the semi-finals of the FA Cup.
This season has been a different story though with Lowry suffering a number of set-backs including injury and suspension, picking up two red cards in matches against Derby County and Sheffield Wednesday.
Along with Lowry, Liam Feeny, Andy Keogh and Jack Smith were also not offered new deals at the Championship club.
"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." Read a statement from the Millwall FC website.
