context_page_description: A rugby ball is an elongated ellipsoidal ball used in rugby football. Its measurements and weight are specified by World Rugby and the Rugby League International Federation, the governing bodies for both codes, rugby union and rugby league respectively.
  The rugby ball has an oval shape, four panels and a weight of about 400 gr. It is often confused with some balls of similar dimensions used in American, Canadian and Australian football.
context_section_description: The rugby ball used in rugby union is a prolate spheroid essentially elliptical in profile. Modern footballs are manufactured in a variety of colors and patterns. A regulation football is 28–30 cm (11–12 in) long and 58–62 cm (23–24 in) in circumference at its widest point. It weighs 410–460 g (14–16 oz) and is inflated to 65.7–68.8 kPa (9.5–10.0 psi).
  In 1980, traditional leather-encased balls, which were prone to water-logging, were replaced with balls encased in synthetic waterproof materials. The Gilbert Synergie was the match ball of the 2007 Rugby World Cup.
  Most of the professional leagues use Adidas, Gilbert, Mitre or Webb Ellis manufactured balls.
