That new date means Warriors will face three senior games in just seven days with Newport (Saturday, December 11), Doncaster (Wednesday, December 15) and Currie (Friday, December 17). The club also has an Aviva A League away date with Sale Jets on Monday, December 13.
However, Hill believes he has the squad to cope with the games and it was crucial for the team to play Doncaster during the British & Irish Cup window and not during the league schedule.
"It will be a challenge for the whole squad. To play three senior games in seven days, plus an A League fixture, is not the ideal scenario, but one we plan to meet head on," said Hill.
"We wanted to rearrange the game during the British & Irish Cup window and will now need to manage the squad.
"We will still be taking the British & Irish Cup very seriously and had planned to play strong sides against Newport and Currie. I will sit down with Phil Davies over the next few days and draw up our provisional selection for all the games and look at how we are going to tackle this fixture list.
"Fortunately all the players in the squad have been kept in really good shape and the rotation system we have used is now very valuable indeed," he added.
"There was always a danger of games being lost at this time of year and midweek rearranged games with no free weekends.
"We have 33 players, out of a squad of 35 we are working with, fully fit and we will do everything we can to send the strongest squads into the game cup games with Newport and Currie as well as out rearranged game with Doncaster.
"Our strength and conditioning team and our medical department have worked very hard to make sure we can cope with this kind of scenario.
"We have real strength in depth in the squad to deal with this and I believe, just before Christmas, it also will create a real competitive environment with everyone out to impress before the Boxing Day fixture with Moseley Rugby."
