Tony Rea says Bradford Bulls are in for a 'rollercoaster ride' after having their six-point deduction appeal rejected and must 'drag others into the fight'.
An independent panel refused the appeal on Thursday, which leaves the Bulls six points from safety in the Super League drop zone.
Bradford were docked six points by the RFL's board of directors on February 25 after entering administration for the second time in two years.
Rea told Boots 'N' All that the Bulls have to focus on the fixtures in front of them and first, must win their game against Salford Red Devils - who are three points ahead - on Sunday at the AJ Bell Stadium.
"It's going to be a real rollercoaster ride for them," said the former London Broncos coach. "The little leg of some points from the deduction is not there. The game on Sunday [against Salford Red Devils] is now massive.
"They'll be looking to drag them [Salford] down. They did the job of putting the team one above them there when they dragged Wakefield closer to them last weekend.
"They have to win games like Salford and drag them closer in to the fight. They need London to aim up - that's not vital - because, don't forget, at some point Wakefield play Salford with three games to go until the end of the season.
"All those things become a bit of a connumdrum but the key is, go out and play well as a team and you've got a chance.
"They really must win on Sunday and get themselves right up tight and make the others sweat."
Sky Sports expert Barrie McDermott added, "What it does do is give clarity to the issue; there were some if, but's and maybe's.
"If you look at the compeititon ladder there's six points between Wakefield and Bradford and that's not coming back unless they earn it on the field.
"When you look at the fixtures coming up you see how difficult the task is for Bradford. I'm sure Francis Cummings will have his players in and say, 'look, this is the job in hand. This is what we've got to do'.
"They did that two weeks ago against Wakefield at home - it was a tremendous perfromance from the players.
"Francis Cummings and the Bradford players know now, what they've got to do."
