However, Jones suffered a dislocated elbow in the last minute of the game after landing awkwardly from an innocuous and accidental clash with the Arsenal left-back Bob McNab. The injury meant Jones missed the League title decider against Wolves a few days later which cost Leeds the championship. Leeds lost 2–1 and the title went to Derby County. Perhaps his finest performance of the 1971–72 season came on 19 February 1972, when he scored a hat-trick against Manchester United in a 5–1 league win at Elland Road.
