[3] Clark was a skilful left-winger who began his career at Leeds United as a teenager in the 1950s, but never broke into the first team at Elland Road.
He spent nine years at the Hawthorns, forming part of an attacking force which later included Tony Brown, Jeff Astle and Bobby Hope.
He returned to QPR briefly in 1969, before signing for Preston North End in 1969-70, making his debut against Bristol City on 24 January 1970.
Clark moved to Southport in 1973, where he ended his career after just one season in the Third Division, playing eight league games and scoring once.
A minute's applause was held in his memory prior to West Bromwich Albion's final game of the 2013–14 season, at home to Stoke City.
