The Scottish-born inside forward, who made 44 appearances during a five-year spell at Wolves, was the club’s oldest surviving former player.
Before his relatively short stay in the Black Country, a young Walker played for the junior club side Campsie Black Watch, going on to represent British Army on several occasions during his National Service.
Walker joined Wolves in 1947 and was at the club during the successful 1948/49 FA Cup campaign, which culminated in a final win over Leicester City at Wembley.
Although Walker was not part of the final team, he flourished in gold and black during the subsequent seasons, making his debut in February 1950 during a 1-0 home win over Portsmouth.
He scored twice in a victory over Derby County a week later before adding two more against Arsenal as part of an eight-goal haul in the final 12 games of the season.
Walker continued his fine form into the 1950/51 season when he netted 16 times in 27 matches, including five goals in an FA Cup run that finished in a semi-final defeat against Newcastle.
Following his five seasons with Wolves, Walker made the switch to Southampton, scoring 48 goals in 172 league games during his time at The Dell.
In 1957, Walker signed for Third Division Reading, spending almost eight years with The Royals, making 318 appearances in blue and white – several of those as captain.
After retiring from his playing career, Walker went on to coach Reading’s reserves and youth team on a part-time basis, alongside his job in a local post office.
The thoughts of everyone at Wolves are with Johnny’s family and friends at this sad time.
