Prinsep played for Clapham Rovers, and also formerly held the record for being the youngest player to play in an FA Cup final, playing in the 1879 final against Old Etonians at the age of 17 years and 245 days. This record was broken not long after his England record, by then Millwall player Curtis Weston, who played in the 2004 final aged 17 years and 119 days.
