The Blue and Blacks were due to face their Gwent counterparts at Cardiff Arms Park but gale force winds due to Storm Dudley has caused minor damage to stadium infrastructure, which cannot be safely inspected in current conditions.
All pitch access today has therefore been postponed to ensure player and spectator safety with full inspections planned for tomorrow morning.
Both Cardiff and Dragons Under-18s go into the Championship decider unbeaten, with the Newport-based outfit currently one-point ahead, having secured a maximum 15 points from their three previous encounters.
