Banner was signed by Salford in March 1967 from Spotland Rangers, and went on to make 180 appearances for the club.[citation needed]
Banner played in three consecutive Lancashire Cup finals with Salford. He scored a try in Salford's 25–11 victory over Swinton in the 1972 Final at Wilderspool Stadium, Warrington on Saturday 21 October 1972. He also played in the 9–19 defeat by Wigan in the 1973 Final on Saturday 13 October 1973 (also held at Wilderspool Stadium, Warrington),[3] and played in the 2–6 defeat by Widnes in the 1974 Final at Central Park, Wigan on Saturday 2 November 1974.
Banner lost his place in the starting lineup following the arrival of Steve Nash,[4] and in September 1975, he was signed by Featherstone Rovers for £4,500.[5] Banner made 21 appearances for the club during the 1975–76 season.[6]
In August 1976, he signed for Leeds for a fee of £5,000.[7] Banner won the 1976 Yorkshire Cup with Leeds, winning 16–12 in the final against his former club Featherstone Rovers on 16 October 1976. He also helped Leeds reach the 1977 Challenge Cup final, but did not play in the final itself, as he had left the club to emigrate to Australia.[4]
Although born in England, Banner was eligible to represent Wales due to his Welsh ancestry,[8] and was selected to play for the team in the 1975 European Championship and 1975 World Cup. He won nine caps for Wales, playing both games at the European Championship and seven matches in the World Cup.[1]
