A tight race for promotion from the Second Division saw the two automatic promotion places decided on the final day of the season, with Leeds United going up as champions after an eight-year exile from the First Division, followed by their
Yorkshire rivals Sheffield United, who finished runners-up to clinch a second successive promotion and end their 14-year absence from the First Division. Swindon Town beat Sunderland 1–0 in the playoff final to secure a First Division place for the first time, only for promotion to be withdrawn weeks later for financial irregularities. The
Football League promoted Sunderland to the First Division in their place, and demoted them to the Third Division, although they were allowed to remain in the Second Division on appeal. Newcastle United, whose new signing Mick Quinn topped the Football League goal charts with 32 goals, had squandered their chance on an immediate return to the First Division by losing to Sunderland in the playoff semi-finals. Blackburn Rovers, who had last played First Division football in the mid-1960s, lost in the other semi-final. Two of the teams who just missed out on the playoffs enjoyed memorable cup runs. West Ham United reached the semi-finals of the League Cup, while Oldham Athletic were semi-finalists in the FA Cup and beaten finalists in the League Cup. Stoke City were relegated to the Third Division after finishing bottom of the Second Division, and were joined in the drop zone by Bradford City and AFC Bournemouth. Middlesbrough, who finished fourth from bottom, narrowly avoided a second successive relegation.
