Wigan defeated St. Helens 13-8 in the Challenge Cup Final at Wembley Stadium before a crowd of 75,532.[2] Denis Betts, Wigan's second row forward, was awarded the Lance Todd Trophy for his man-of-the-match performance.[3]

In Hull's 14-4 victory over Widnes in the 1991 Rugby League Premiership Final at Old Trafford, Manchester on Sunday 12 May 1991, their captain and stand-off; Greg Mackey, was named man of the match, winning the Harry Sunderland Trophy at Old Trafford in front of 42,043, a record crowd for a Premiership Final at the time.

The months of October and November also saw the appearance of the Australian team in England on their 1990 Kangaroo Tour. Other than the three test Ashes series against Great Britain (won 2–1 by Australia), The Kangaroos played and won matches against 8 Championship teams (St Helens, Wakefield Trinity, Wigan, Leeds, Warrington, Castleford, Hull and Widnes), 1 Second Division side (Halifax) and one county side (Cumbria). The team was coached by 1973 tourist and 1978 tour captain Bob Fulton and was captained by Mal Meninga who was making his third Kangaroo Tour as a player.

Penrith Panthers halfback Greg Alexander (who played most of the tour as the backup fullback to Gary Belcher), was the leading point scorer on the tour with 156 from 14 tries and 50 goals. Like Terry Lamb on the 1986 tour, Alexander was selected for every match on the tour, but he did not get off the bench in the 2nd Ashes Test at Old Trafford. Cronulla-Sutherland outside back Andrew Ettingshausen was the leading try scorer with 15 including hat-tricks against St Helens in the tour opener and Wigan a week later.

Great Britain's win in the first test at Wembley was the Lions first test win on home soil over Australia since 5 November 1978. It was the Kangaroos only loss of the tour.
