Nottingham director of rugby Glenn Delaney insists he has not given up on qualifying for the Championship play-off semi-finals.
The Green & Whites must win their final two matches of the season and collect bonus points, while hoping that Bristol can beat London Welsh this weekend.
"The objective is to go to Doncaster and keep the pool alive," Delaney told BBC Radio Nottingham.
"We don't need miracles. We have to focus and then what will be will be."
Nottingham are third in Pool A after four games, 10 points behind leaders London Welsh.
Second-placed Bristol are eight points ahead of Nottingham and are expected to beat Doncaster in their final pool game.
Nottingham complete their fixtures at home to London Welsh.
"The reality is we need to have it in our own hands," said Delaney.
"We need to go into that game with London Welsh on the final day needing a bonus point win to go forward. We can't rely on Doncaster to go and win at Bristol."
Doncaster sit bottom of Pool A with just one point from four matches.
"There'll be a siege mentality from Doncaster, with it being their last home game of the year," added Delaney.
"They've had a poor playoffs, they won't think they've had a great season, so they'll be looking for one last hurrah.
"I'm always confident we can score tries, we've had a top-four attack all season against all the teams, and our try record is pretty good.
"All we can control is our level of performance.
"I feel like we've got to a point I'm happy with, now we just have to repeat that."
