The first Danske Bank Schools' Cup semi-final has been rearranged due to the weather.
Defending champions Inst will play Royal School, Armagh in the final four on Wednesday, March 5. The game had been scheduled to be played on Monday, but has been pushed back 48 hours.
Campbell College, meanwhile, will play Methody in the second semi-final as a repeat of the 2017 final remains a real prospect.
Last year's runners-up Methody were the biggest winners of the quarter-final morning, cruising to a 53-10 success over Bangor Grammar.
Both matches will be played at Kingspan Stadium. The first-named teams will use the home changing room for their semi-finals. The winners of the RBAI v Royal School, Armagh tie will use the home changing room in the final, which is scheduled for Monday, March 19.
