Boyd made his debut for Killie as a teenager against Celtic on the final day of 2000/01 and went on to enjoy a goal-laden career in the top flight of Scottish football.
He was the record goalscorer in the SPL era and was presented with a Golden Boot in January 2010 after surpassing Henrik Larsson's tally of 158 goals by netting five times in a 7-1 win over Dundee United. He also scored five goals in one game for Kilmarnock, with Dundee United again the victims.
In all, Boyd netted 121 league goals for Kilmarnock and 104 league goals for Rangers, as well as scoring on seven occasions for Scotland.
His career also included spells at Middlesbrough, Nottingham Forest, Eskisehirspor and Portland Timbers but he will best be remembered for his scoring exploits at Rugby Park and Ibrox.
