Career
West Bromwich Albion spotted Dennison at Irish club Glenavon and signed him on a two-year deal in September 1985. He also appeared for the club at Wembley in the Football League Centenary Tournament just a month earlier, scoring a long range goal against Everton. In total, he made over 300 appearances in total for Wolves, scoring 49 times.
His appearances began to become more limited with the arrival of Graham Taylor at Molineux in the mid-1990s and he went on loan to Swansea City in 1995, before moving to non-league Hednesford Town in 1997 and in 1999 had a brief spell with Halesowen Town.
He rejoined with one-time boss Graham Turner at Hereford United, and later became player/manager at Warley Rangers. Dennison made 18 appearances for Northern Ireland, spread over a 10-year period.
His debut came on April 27, 1988 in a goalless friendly with France. Since retiring, he formed a sports trophy business and currently provides co-commentary on Wolves matches live on Beacon Radio.
