Sean Kelly: AFC Wimbledon sign former St Mirren defender

Sean Kelly made a total of 90 league appearances over the last three seasons at St Mirren

League One newcomers AFC Wimbledon have signed defender Sean Kelly following a successful trial spell.

The 22-year-old Scotland Under-21 international was a free agent after leaving Scottish Championship side St Mirren earlier this summer.

Kelly, who can play at centre-back or left-back, becomes Wimbledon's sixth signing of the summer transfer window.

"We wanted someone young who we could develop," Dons boss Neal Ardley told the club website.

The south-west London club have not disclosed the length of Kelly's contract at Kingsmeadow.
