Richards is an U18's striker and has been given a scholarship at the Sky Blues.
"Everyone at the club wishes Courtney every success, and like Liam Mayer who joined Walsall FC last season, we will follow his progress at the higher level," said Romulus' Youth Director Mark Taylor, according to Non-League Daily.
"Of course we are sorry to see such a talented lad leave us and as a player and a person he will be sorely missed.
"But a chance to play at that level doesn't come along every five minutes so we are delighted for him, he definitely has the ability to make an impact."
