Speaking about the game, Ravens manager Gary Longwell said: "This is a young Ravens team with a number of new faces mixed in with established Ulster squad members and Phoenix Ulster Rugby Academy players.
"Ballymena's Steve Castle gets a run in the centre beside Michael Allen who, along with full-back Paddy Robinson, caught the eye in the past two Schools Cup finals playing for Methody.
"Niall Annett makes a welcome return following an elbow injury at the start of the season, and will captain the side from hooker.
"Paddy McAllister, Adam Macklin, James Sandford, Neil McComb and Ali Birch have all featured for the Ravens already this season and with Paul Marshall at scrum half, they are sure to be kept on their toes.
"The bench also has considerable talent available with Niall O'Connor's younger brother Mark and Ballymena's Tommy Seymour ready to add plenty of pace to the proceedings.
"Instonians flanker Paddy Marks is the back row cover along with Ballynahinch second row James Simpson.
"Dungannon scrum half Jason Bloomfield is cover for Marshall with Dromore's Jonny Simpson on standby should Malone prop Darryl Maxwell not pass a late fitness test."
