The game was scheduled to be played today but has been delayed due to the adverse weather conditions.
A statement from Nottingham read: "We apologise for any inconvenience caused but the game against Doncaster has been postponed.
"Playing the game on Tuesday is, however, subject to the temperature rising above five degrees on Monday."
It will be an intriguing contest should it beat the weather, with Nottingham just three points below fifth-placed Doncaster in the table with two games in hand.
The two teams conspired to produce 88 points when they met at Castle Park in October, with Doncaster edging the game 46-42.
The fixture pits together two of the league's top points scorers in Nottingham fly-half James Arlidge who averages 13 of Nottingham's 31 points a game to be the division's top kicker, and Tristan Roberts, the Knights No 10, who is the third-highest points scorer with an average of over nine points a game. He has kicked 12 fewer points than Arlidge.
Injury-wise, Doncaster are struggling in the forwards.
Andy Boyde, a player who grows in stature every season at Castle Park, is out for the foreseeable future while Ed Jackson will be out for four to five weeks with ligament problems.
Inspirational Glen Kenworthy is still recovering from a broken neck but there is a silver lining in the possible return of vice captain Neil Cochrane for the game at Meadow Lane.
