In 1947, the nations of Great Britain joined together to form a football team, which Hardwick captained and led to victory (6–1) against the rest of Europe.
Owing to a knee injury Hardwick had to terminate his international career after 12 matches. He is held in high esteem by Middlesbrough fans, and is regarded as the greatest defender in the club's history.
Today his legacy lives on in the form of The George Hardwick Foundation, a charity dedicated to helping carers, former carers and patients. The Patron is his wife Jennifer, who cared for George during his latter years. They have three main sites at Stockton, Middlesbrough and The University Hospital of North Tees.
