Gordon Jones stands second with the most appearances for Boro and the man who has played the most post-war games for the club.
Playing 527 times for the club, Jones became a permanent fixture at left back for the club for a decade.
He gained honours with England Under-23s but never claimed senior international honours with the Three Lions.
Beginning his Boro career at right back, Jones eventually became a mainstay at left back when he replaced England international Mick McNeil.
Never dismissed in his long career and only booked on two occasions, Jones wore the captain's armband for six seasons for Boro, including the promotion-winning season in 1967 under Stan Anderson's stewardship.
He scooped the club's Player of the Year award twice - in 1966 and 1971, with his time at Boro coming to an end two years after collecting the individual prize when he lost his place in the side to Frank Spraggon.
Jones signed for Darlington on a free transfer, but retired shortly after in 1975.
