In rugby, each team has 15 players on the field and seven substitutes. Rugby is closely related to soccer and American football.
In 1823, a school in Rugby, England created a modified version of football, the precursor to soccer and American football. In 1871, the Rugby Football Union was formed, and in 1886, the International Rugby Football Board established some rules for the sport. Rugby was recognized as a professional sport in 1995.
Rugby is similar to soccer and American football, as it is played on a grass field with a goal on each end. It begins with a kick-off, and the ball can be passed only laterally or backwards. The ball can be kicked, and tackling is permitted. Scoring is called a "try" and is executed much like a touchdown. Rugby sevens is another form of rugby in which each team has seven players.
