Fall
1876
On Nov. 30, 1876, Princeton and Yale faced off in Hoboken, N.J., playing what would best be described as an 11-on-11 form of rugby.
Princeton entered the game with a 3-0 record and a fresh set of uniforms — black tights and jerseys with an orange P on the chest — but the Elis prevailed, two goals to none. The Princetonian, then in its first year of publication, questioned a few key calls by the referee, noting that he was “a Yale man.”
