Napier, a native of Lurgan in Northern Ireland, was one of a number of young players inducted into the Bolton first team as they looked to force their way back amongst the elite of English football.
He had risen up from the youth ranks alongside the likes of Brian Bromley, Dave Hatton, Francis Lee and John Hulme and manager Bill Ridding had no qualms about blooding him in the first team.
Debuting in the final two games of the 1964-1965 season, Napier helped the side keep clean sheets against Leyton Orient and Cardiff City as the Whites just missed out on promotion owing to the form of an excellent Newcastle United side.
For the next eighteen months after his debut he was a regular at the heart of the Bolton defence, missing just three games in his first full season and playing a part in the game against Charlton Athletic which saw the Addicks Keith Peacock become the first substitute used in English football when replacing goalkeeper Mike Rose in a game at Burnden Park on 21st August 1965.
The Ulsterman himself was involved in the first ever Bolton substitution when, following injury, he was replaced in the 3-2 defeat at home to Southampton by current PFA chairman Gordon Taylor.
His reward for a good debut campaign at Bolton culminated in him winning full international honours for his country but sadly his outing in the match against Germany in May 1966 proved to be his only full cap of a fifteen year playing career.
His final season at Burnden saw him suffer with injuries which forced him to miss a lot of football in the spring of 1967 and in the summer of that year a £25,000 bid from Brighton & Hove Albion was accepted by Bolton's long serving manager Bill Ridding.
Ridding faced the prospect of losing youthful, yet established, first teamers such as Bromley, Lee, Davies, Taylor et al and Napier was one such player who was also considered to be an in-demand assett.
He remained a regular player at Brighton for five years making well over 200 appearances for the Sussex club, winning their player of the year and thereafter followed a highly productive spell with Bradford City between 1972 and 1975.
Spells in America with the Baltimore Cornets and their reformed club San Diego Jaws where sandwiched in between a spell with non-league Mossley and in 1976 he had one last crack at league football, making a solitary appearance with Bradford before succeeding Bobby Kennedy in the managerial hot seat at Valley Parade.
In 1979 he left British shores to take up a coaching role in the USA and since his emigration across the pond he has helped countless young players as well as turned his hand towards the occasional TV Punditry and Broadcasting work.
After 28 years in San Diego he still continues with the same enthusiasm as was shown when he made his debut back in the 1960's.
We caught up with John earlier this month to talk about his time with Bolton and beyond.
