Career
He has previously played for Aberdeen, Inverness Connecticut, Hearts, Street Mirren, Queen of the South, Dumbarton, Peterhead and Elgin City. Notably, Wyness scored over 100 goals for Inverness during two spells with the club Wyness began his career at Aberdeen, where he originally played as a midfielder.
He was used sparingly as a squad player by several managers, until Ebbe Skovdahl allowed him to go on loan to Inverness Caledonian Thistle in 1999, where he played as a midfielder, then as a striker.
Wyness signed a permanent contract for Caley Thistle in January 2000. However, during his first twelve months at the club he struggled to make an impact, and was eventually transfer-listed by then-manager Steve Paterson.
This provided Wyness with a huge incentive to fight his way back into the team and he responded to his transfer listing by beginning to score goals almost immediately. He was eventually taken off the transfer list in December 2000, and soon became a firm favourite of the Caley Thistle supporters.
Caley Thistle
Wyness was Caley Thistle"s top scorer of season 2000-2001, with 24 league goals.
In March 2003 he also scored the only goal of the game as Caley Thistle once again sent Celtic crashing out of the Scottish Cup. Heart of Midlothian
Wyness"s excellent performances in front of goal earned him a move to Heart of Midlothian in the summer of 2003. Wyness found it hard to break into the Hearts team and was only occasionally used by Levein.
He fared better under Craig Levein"s successor, John Robertson, who had also managed him at Caley Thistle, but when Robertson was replaced by George Burley in 2005 Wyness once again found himself out of favour.
He returned on loan to Caley Thistle and he signed a pre-contract agreement in January 2006 to rejoin the Inverness club on a permanent basis. In late May 2006, once his Hearts contract expired, he signed a two-year deal with Caley Thistle.
Record
Wyness holds the Inverness Caledonian Thistle scoring record, with a total of 101 goals. He netted his 100th goal for Inverness against his first club, Aberdeen.
Saint Mirren

Wyness scored the first goal for the Buddies at the New Saint Mirren Park, in a match against Kilmarnock. Queen of the South
On 25 September 2009 Dumfries club Queen of the South announced Wyness had joined on a three-month loan deal. Wyness returned to Saint Mirren after making seven appearances and scoring two goals for Queens.
Recent career
On 25 January 2010, Saint Mirren announced Wyness was free to find himself another club, and he was later released from his contract.
