Born in Rowlands Gill, County Durham, Clark joined the Magpies from Crook Town in October 1962 and would remain at St. James’ Park until 1975.
An accomplished, dependable left-back, Clark became a first team regular during the 1964/65 season as Newcastle United lifted the Second Division title.
Four years later, in 1969, Clark would taste European glory for the first - but not the last - time in his long career as the Magpies lifted the Inter-Cities Fairs Cup.
He reached the FA Cup final with the club in 1974 before moving to Nottingham Forest a year later, where he would go on to become a league and European Cup winner.
