Rugby is the first sport in school for boys.
All years have their own rugby divisions.
Each division usually boasts more than one team. Games are usually played on Wednesdays or Saturdays against rival schools. The college enters teams for both the Lenister School's Senior Cup and Junior Cup. Although the college has not had much success in recent years in these competitions, the fighting spirit and determination of Newbridge teams is a force to be reckoned with. Newbridge College play in black and white jerseys, black shorts and black socks.
