Greacen started his career as a youth player with Rangers, before making his first competitive appearances with Airdrieonians. Following only three league games, he was signed by the at-the-time Scottish Premier League side Livingston where he spent most of his time on loan at Queen of the South and Morton.
After leaving Livi, he played for Forfar Athletic before moving on to become captain at Morton where he had previously been on loan.
He began his senior career at now defunct Airdrieonians and from there he moved to Livingston. Livingston then sent him on loan to Queen of the South and Greenock Morton, where he played in the team that was relegated from the Scottish Second Division in the 2001–02 season. Livingston released Greacen in 2003 and he was immediately signed by Forfar Athletic. He played the second half of the 2002–03 season season at Forfar on a short-term contract. At the end of the season Forfar offered Greacen a long term deal which he rejected in favour of a deal at Morton. The main reason for this was that Morton offered a full-time contract in comparison to Forfar's part-time contract.
Greacen plays at centre back in the Morton defence. He is a tall commanding defender with a strong physical presence. He is good in the air and this helps in both an attacking and defensive way as he often scores from headers at set pieces. At 24 years old, Greacen became Greenock Morton's captain.
In May 2008, it was announced that Greacen had rejected a new contract from Morton and was being tracked by rival Scottish First Division sides Dunfermline Athletic, Queen of the South and Livingston.
Greacen was Morton's Player of the Year for 2008–2009.
On 22 December 2010, Greacen was released by Morton after nearly 250 appearances over two spells from the club.
He linked up Glentoran on 21 December 2011 but was released from his contract at the end of January 2012 as he wished to play full-time football again and has found the travelling from Scotland and not being able to train with the Glentoran squad an issue. He then joined up again with former club Derry City for training, admitting that he was in talks to sign a new contract. He subsequently rejoined them.
