A ground inspection at Bready on Monday rated the chances of play as 50:50 with the outfield and run ups still very soft following a deluge on Saturday night.
The ground conditions forced the Warriors to train indoors ahead of the clash with Northern Knights.
The sides scheduled opener last week at Shaw's Bridge fell victim to the elements, and both sides will be hoping for favourable weather conditions in what has been another weather plagued interprovincial season.
Ryan Hunter (work) is the only absentee for the Warriors, while Conor Olphert, although able to train today, isn't risked by Head Coach Ian McGregor.
The Warriors have never won the 50-overs format, while the Knights sole triumph came in the inaugural year of the revamped interpros back in 2013.
There were several injury fears for the Knights, with Mark Adair (side strain) missing Saturday's All-Ireland T20 semi-final, but he has been passed fit. His CIYMS team mate Jacob Mulder misses out though.
Play at Bready (hopefully) gets under way at 10:15am and the game will be live scored on CricketEurope.
