Defender. Cultured defender Sheehan joined the Hatters on loan from Bradford City last January, becoming Nathan Jones’ first signing after taking over as manager. The deal was made permanent in the summer of 2016. The Irishman made 20 appearances and captained the team for the final seven matches after Scott Cuthbert suffered a season-ending injury at Stevenage in early April. The left-footer can operate at either full-back or in central defence, and has made over 300 appearances in his career so far with the majority coming during two spells with Notts County. Sheehan also counts Leeds United and Swindon Town among his former employers, as well as loans with Mansfield, Crewe, Oldham and Peterborough United, after starting out at Leicester City.
