Career
This was during the era of contested scrums. He went on to coach at club level for Castleford, Leeds and Doncaster. Sheridan was a Tigers Hall Of Fame Inductee.
He joined Castleford Tigers from local side Castleford Lock Lane, choosing his home town club over Leeds outfit Hunslet.
During the early part of his career he was a strong running centre who regularly topped the clubs try scoring lists. After the 1958/59 season John moved into the pack and took up the loose forward role.
He was named captain as the club began to climb the league table in the early 1960s. Injuries took a toll and he moved into coaching.
From 1964-1982, Sheridan was "A" team coach at Castleford, winning nine Yorkshire Senior Championships and six Yorkshire Senior Cups.
He returned to coaching at Doncaster RLFC and turned the club around. He was voted the most influential person in the clubs history by the Dons fans. Sheridan was born in Pontefract, of Irish and English parentage, and grew up in the Wheldon Lane area of Castleford in a large Catholic family.
As part of his National Service he joined the Royal Air Force for two years, mainly working as a bar man in the officers mess and playing Rugby Union.
Once back in Castleford he signed for the Tigers and also worked in industry alongside his rugby career.
