Passage: Rugby football refers to the team sports of rugby league and rugby union.Rugby football started about 1845 at Rugby School in Rugby, Warwickshire, England, although forms of football in which the ball was carried and tossed date to medieval times. Rugby split into two sports in 1895, when twenty-one clubs split from the Rugby Football Union to form the Northern Rugby Football Union, renamed the Rugby Football League in 1922, in the George Hotel, Huddersfield, over broken-time payments to players who took time off work to play the sport, thus making rugby league the first code to turn professional and pay players. It was a hundred years later in 1995, following the 1995 Rugby World Cup in South Africa, that rugby union turned fully professional. The respective world governing bodies are World Rugby (rugby union) and the Rugby League International Federation (rugby league).

Question: Along with World Rugby what other group oversees the professional rugby sport?
Rugby League International Federation
