Question: Which goalie played for Manchester CIty against Birmingham City in 1955-1956 FA Cup with a broken neck?

full_context: Document 1: History of Birmingham City F.C. (1965–present): Businessman Clifford Coombs took over as Birmingham chairman in 1965, and appointed Stan Cullis as manager. Cullis's attractive football took them to cup semi-finals, but league football needed a different approach. Successor Freddie Goodwin produced a team playing skilful, aggressive football that won promotion to the First Division as well as reaching an FA Cup semi-final. Two years later, the club raised money by selling Bob Latchford to Everton for a British record fee of £350,000, but without his goals the team struggled. In 1979, with relegation a certainty, the club sold Trevor Francis to Nottingham Forest, making him the first British player transferred for a fee of £1 million; Francis had scored 133 goals in 329 appearances over his nine years at Birmingham. Jim Smith took Birmingham back to the top tier, but a poor start to the 1981–82 season saw him replaced by Ron Saunders of league champions Aston Villa. The team still lacked goals, and were relegated in 1984. The last home game of the 1984–85 promotion season was marred by rioting and the death of a boy when a wall collapsed; the events formed part of the remit of the Popplewell inquiry into safety at sports grounds. Saunders quit after FA Cup defeat to non-League team Altrincham, staff were laid off, the training ground was sold, and by 1989 Birmingham were in the Third Division for the first time in their history.
