Comber will now be the venue for Tuesday's interprovincial clash between the MTB Northern Knights and NW Warriors.
The match had been scheduled for Waringstown but following a ground inspection at The Lawn this morning, a decision was taken to switch.
The Knights will be at full strength for the game which they must win to keep pressure on Leinster Lightning.
They meet in the penultimate match of the T20 tournament on Thursday at Sydney Parade.
Graeme McCarter is unavailable for that match.
Action tomorrow at Comber starts at 1.30pm.
