IRISHMAN Colin O'Riordan has signed a two-year deal with Sydney to keep him at the club until the end of 2019.

The 22-year-old joins defender Lewis Melican as having been promoted to the senior list.

Sydney will use its last two picks in the NAB AFL Draft on Friday – currently No.84 and 92 – to elevate the pair. 

Robbie Fox, Toby Pink and Ben Ronke will be retained as rookies for 2018. 

O'Riordan joined the Swans as an international rookie at the end of 2015 and is yet to make his debut.

"Such an honour to have signed on for two more years with the Sydney Swans. Love this club," O'Riordan said in an Instagram post. 

Delisted duo Alex Johnson and Sam Fisher are training with the club in the hope of being picked up in Monday's rookie draft.
