In the 2013–14 season, Edgar struggled in the first team, with Michael Duff and Shackhell preferred in the centre–back instead. Throughout the season, Edgar spent the most of the 2013–14 season on the substitute bench. Despite this, Edgar made his first start of the season in the second round of League Cup, in a 2–0 win over Preston North End on August 27, 2013. Then, on October 1, 2013, he made his first league start of the season, in a 2–0 win over Doncaster Rovers. As the 2013–14 season progressed, Edgar played occasionally and spent the season on the substitute bench, resulting him making twenty–one appearances in all competitions. Following Burnley's promotion to the Premier League, Edgar was one of four players released by the club following the expiry of their contracts.
