Arnold Sedgfield “Saturday” Knight was born on 16 December 1885 in Burgersdorp and educated at SACS in Cape Town. A forward by trade, he developed his rugby in the early 1900s playing for Pirates and Transvaal, making his name as a dependable and durable player in a tough era.
Knight earned national honours when he toured with the Springboks in 1912 - 13. He played in all five Tests on that tour - Scotland, Ireland, Wales, England and France - representing South Africa with consistency and strength in the pack. Though not known for flashy flair, he was valued for his work rate, discipline, and reliability among forwards of his time.
Later in life, Knight also took up refereeing, officiating matches including the notable fixture on 20 August 1924, when the British Lions visited Johannesburg and beat the Witwatersrand side 10 - 6. His involvement in both playing and refereeing underlines a lifelong devotion to South African rugby.
He passed away on 1 July 1946 at his farm, Pumala, near White River, Transvaal, at the age of 60, leaving behind a legacy as an early Springbok stalwart and one of rugby’s devoted servants.
