Duncan Cowan Ferguson (born 27 December 1971) is a Scottish football player and coach. He began his professional career at Dundee United in 1990. He moved to Rangers in 1993 for a then British transfer record fee. He spent the remainder of his career in England, with two spells at Everton split by a stint with Newcastle United between 1998 and 2000. Ferguson retired from football in 2006.
During his career, Ferguson won the FA Cup with Everton in 1995. He was capped for Scotland seven times but made himself unavailable for selection for the national team due to a dispute with the Scottish Football Association. He has scored more goals than any other Scottish player in the Premier League.
Ferguson was noted for his aggressive and highly competitive style of play which resulted in nine red cards and a three-month prison sentence following an on-field assault of Raith Rovers' John McStay in 1994. Eight of those red cards were in the Premier League, where he holds the joint-record for dismissals along with Patrick Vieira and Richard Dunne. He was nicknamed "Big Dunc" and "Duncan Disorderly".
