The Portsmouth Spartans were a professional American football team that played in Portsmouth, Ohio from their founding in 1928 to their relocation to Detroit in 1934. Originally drawing players from defunct independent professional and semi-professional teams, they joined the fledgling National Football League (NFL) in 1930. Their home stadium was Universal Stadium, known today as Spartan Municipal Stadium.
The team was sold to a new ownership group in 1934 and relocated to Detroit, where they were relaunched as the Detroit Lions — a team which remains part of the NFL today.
