Gregory played Scrum-half in Widnes' 19-6 victory over Wigan in the 1984 Challenge Cup Final during the 1983–84 season at Wembley Stadium, London on Saturday 5 May 1984, in front of a crowd of 80,116.

[9][10] Andy Gregory played Scrum-half, and was sent-off for stamping on Nick du Toit in Warrington's 8–34 defeat by Wigan in the 1985 Lancashire Cup Final during the 1985–86 season at Knowsley Road, St. Helens, on Sunday 13 October 1985.

Also in 1987, he played a big part in the inaugural World Club Challenge win over Australian champions Manly-Warringah, and although he was only small in height he dominated games on the field from scrum-half.

[14] Gregory appeared as a substitute (replacing Centre Joe Lydon on 51 minutes) in Wigan's 12-6 victory over Widnes in the 1988–89 John Player Special Trophy Final during the 1988–89 season at Burnden Park, Bolton on Saturday 7 January 1989,[15] and played Scrum-half in the 24-12 victory over Halifax in the 1989–90 Regal Trophy Final during the 1989–90 season at Headingley, Leeds on Saturday 13 January 1990.

[16] In 1989, Gregory, and Wigan teammate, fullback Steve Hampson, played several months of the 1989 NSWRL season in the Winfield Cup with the battling Illawarra Steelers.

[18] During the 1991–92 season, Gregory played for defending champions Wigan as a scrum-half in their 1991 World Club Challenge victory against the visiting Penrith Panthers at the famous Anfield stadium in Liverpool.

Gregory was transferred to Leeds in 1992, after feeling he had no option but to leave Wigan when they gave him the terms of his contract extension following his return from the Great Britain Lions tour of Australasia.

Gregory made his début as a substitute in Great Britain's 7–8 loss to France in the friendly at Stadio Pier Luigi Penzo in Venice, Italy on Saturday 31 July 1982.

After Australia had dominated the first two games to wrap up the series, he was named Man of the Match as the British Lions overcame the Wally Lewis led Aussies 26–12 at the Sydney Football Stadium.

[1] He regretted the decision, as he left the tour injured as he had not recovered from a leg strain that he received at the end of Wigan's season, and it was this injury that prompted the club's desire to sell him.

In 1995, Salford were excluded from the top division because of their resistance to a merger with nearby club Oldham, and despite finishing six points clear of the relegation zone.

[25] In 1996, Gregory also coached the Great Britain Nines side for the twelve nation World Cup in Australia,[26] leading them to the semi-finals before an eventual loss to Western Samoa.

The book was warmly received by fans, despite some stories that were easily contested, including his description of a Wigan versus Halifax match that actually took place after he had joined Leeds.
