Rainey Old Boys started out life as Magherafelt RFC. Magherafelt RFC was founded in 1928. Some success at minor level came the club's way before the outbreak of war.
A few games were played during the war years and from 1947, the club became known as Rainey Old Boys RFC.
Former Ireland captain Willie Anderson has stepped down as Rainey's coach this season. He said: "I enjoyed a fabulous year with players who wanted to change, learn and develop."
