Copping was born in Middlecliffe, Barnsley, Yorkshire, but was rejected by his local team Barnsley, and worked for a time in the pits while playing for Middlecliffe Rovers. He eventually joined Leeds United in 1929, and made his debut at the start of the 1930-31 season, soon becoming a regular in the Leeds half-back line. Together with his Leeds United teammate Billy Furness, he made his debut for England, against Italy on 13 May 1933. Copping played over 160 League games for Leeds in five seasons, and won six England caps during that time.
Arsenal
Copping was signed by Arsenal in the summer of 1934 for £8,000, as a replacement for Bob John, and immediately took a first-team place at left half. He made his debut against Portsmouth on 25 August 1934, and was an ever-present in his first season for the club, until suffering a serious knee injury in the third-last match of the season against Everton. Copping soldiered on and remained on the pitch to ensure Arsenal won the game 2–0; this ensured the club won the 1934-35First Division title. Copping recovered from his injury to continue playing for Arsenal, making over 35 appearances in each of his first four seasons with the club. During his time at Highbury, Arsenal won the FA Cup in 1935-36, another League title in 1937-38, and two Charity Shields. His England career also continued, and he was one of seven Arsenal players to start England's match against Italy in November 1934 - a game for which he named man of the match. In total he won 20 caps for England between 1933 and 1939. He remained a near-ever present for Arsenal until March 1939; with World War II looming, Copping put in a transfer request so that he could return to the North with his family. Arsenal duly complied, and Copping re-signed for Leeds United. In all he played 189 matches for Arsenal.
Return to Leeds United
Copping played out the rest of the 1938-39 season with Leeds United, but war broke out in September 1939 and all first-class football was cancelled. Copping joined the Army at the start of the war, and served in North Africa, eventually becoming a Sergeant Major. He played the occasional wartime game for Leeds, but retired from playing football in 1942. Copping was known as a hard and strong player; his most famous quote was "the first man in a tackle never gets hurt". Despite his nickname of "The Iron Man", and his image, Copping was never booked or sent off in his career.
