In February 2002 he was invited to train with Nottingham Forest and subsequently played a huge role in their youth team's Dallas Cup success.
Despite for the most part enjoying his second season at Diamonds, Tynan requested his contract be cancelled by mutual consent after a mixture of becoming disillusioned by then manager Garry Hill and a desire to be closer to his home in Liverpool.
In August 2006, Tynan was loaned to Hereford United for a short spell as emergency goalkeeping cover for Wayne Brown who was injured in the opening game of the season against Stockport County.
During this loan spell Tynan enjoyed a good run of form and played his part in some memorable games, most notably the 3–0 defeat of Coventry City in the League Cup.
After a trial at Morecambe Tynan signed for Ebbsfleet United on 10 August 2007, a day before the new season, to cover for Lance Cronin who sustained a finger injury.
He was part of their most successful season in recent times helping them reach the 1st round proper of the FA Cup in which they faced Hartlepool United who were then second in League 2.
