A gifted player, he broke the Featherstone Rovers' record points scored in a season, the next winter and was called up for England's game against France.
[8] Fox played loose forward in Wakefield Trinity's 21–9 victory over St. Helens in the Championship Final replay during the 1966–67 season at Station Road, Swinton on Wednesday 10 May 1967, and played at prop, and scored a goal in the 17–10 victory over Hull Kingston Rovers in the Championship Final during the 1967–68 season at Headingley, Leeds on Saturday 4 May 1968.
[9] Don Fox played at prop, and scored two conversions in Wakefield Trinity's 10–11 defeat by Leeds in the 1967–68 Challenge Cup "Watersplash" Final during the 1967–68 season at Wembley Stadium, London on Saturday 11 May 1968, in front of a crowd of 87,100.
Tries were worth three points at that time, making the score 11–10, but a simple 2-point conversion was all that was needed to give Wakefield an unassailable one-point lead, and win the game.
However, the waterlogged state of the pitch made this a more difficult proposition, and Fox lost his footing and sliced the ball wide of the posts.
He later moved to loose forward, where he earned his sole Test cap for Great Britain against Australia in 1963, scoring one try and two goals in a 16–5 win.
