Recruited from Moe Football Club, he played his first match for the Essendon senior team in Round 5 of the 1960 season, against Carlton, at Essendon's home ground, Windy Hill. He played on the half-forward flank, kicking 96 goals in his 106 game career. He played in the 1962 Essendon premiership team that beat Carlton 13.12 to 8.10.
Within the first 10 minutes of the 1965 Preliminary Final between Essendon and Collingwood Somerville was knocked unconscious by his opponent, the Collingwood half-back flanker Duncan Wright. At the time, Wright and Somerville were some 90 metres behind the play and were isolated by some 30 metres from all other players, and were much closer to the boundary than they were to the central goal-to-goal line. Somerville was so badly injured that he was taken off the field on a stretcher and was taken to hospital immediately. Due to the severity of his injuries, he was unable to play in the following week's Grand Final. Essendon, backed by a now polarised crowd, went on to beat Collingwood 14.21 to 6.6.
Aftermath
There was a public outcry; and the press was outraged: The police made some preliminary enquiries. The match officials, the field umpire Ron Brophy, the two boundary umpires, and the two goal umpires all claim to have seen nothing. The field umpire, Ron Brophy, was never selected to umpire a VFL match again. Wright, too, denied everything. However, many years later, Wright openly admitted that he had indeed felled Somerville, and claimed that his actions had been in response to Somerville's niggling — which had started from the moment that the taller, far more skilful Somerville had been swapped over, by Essendon's coach John Coleman, from his selected position on the opposite half-forward flank, to play on Wright. Wright, was renowned for his hot-headed violence: The Collingwood coach, the tough champion rover, the highly talented boxer, and the scrupulously fair man Bob Rose was far from impressed with Wright's knockout; and, at Rose's behest, during the 1966 pre-season practice matches – that is, when the police, VFL and general social pressure on Collingwood and Wright had somewhat diminished – Wright was told, by football club secretary Jack Burns that his services were no longer required at Collingwood. He never played another VFL game.
