Wallace Duffy (born 12 April 1999) is a Scottish professional footballer who plays for Scottish League One club Inverness Caledonian Thistle as a right-back or a centre-back.
Duffy began his career with Rangers,[1] before playing for Celtic, making one appearance for their under-20s team in the Scottish Challenge Cup. He signed for St Johnstone in June 2019,[2] and stated his intention to break into the first-team.[3]
In September 2020, St Johnstone agreed to loan Duffy to Greenock Morton for the 2020–21 season,[4] but days later this deal was cancelled due to "non-footballing reasons".[5] He was released by St Johnstone in October 2020.[6] Later that month he signed for Inverness Caledonian Thistle.[7] Duffy confirmed his departure from Inverness following the conclusion of the 2023–24 season after not receiving a new contract offer from the club.[8] On 10 August 2024, Duffy re-signed for Inverness Caledonian Thistle on a two-year deal.[9]
Duffy has represented Scotland at under-17 and under-19 youth levels.
