In December 2011, with Hearts experiencing financial difficulty, Glen was told that he was free to either find a new club in the January 2012 transfer window, or he would be released when his contract expires in summer 2012. He made his first appearance of the season after recovering from injury as a substitute on 7 January 2012 as a substitute against Auchinleck Talbot in the Scottish Cup. Glen scored his first goal of the season on 7 April 2012, in a 2–1 victory over Dunfermline. At the end of the season Hearts confirmed his contract had not been renewed and he left the club.
