Talismanic player-coach Paul Cooke insists that getting a bonus point in the Dewsbury defeat does not take the edge off their first loss of the season.
Doncaster went into the tie on an equal footing with the Rams having won their two opening Championship matches.
And the Dons went ahead through Scott Spaven before Dewsbury Ram-raided their opponents in a physical battle at the Keepmoat Stadium, claiming a 20-12 victory.
“We are not at a level where we accept defeat and we accept picking up bonus points,” said Doncaster stand-off Cooke who scored his side’s second try.
“It is testament to the players’ belief and how hard they work and their expectations. They expect more and demand more as a group.
“The bonus point doesn’t interest me, the loss is a loss and we will fix it up and we will move on.”
Facing high-flying Dewsbury, a side Doncaster failed to conquer in three meetings last season, neither could be separated with a 0-0 ensuing at the break - only Cooke’s second goalless scoreline at half time in his playing career.
Despite Doncaster scoring first through Spaven and Stewart Sanderson converting, Dewsbury responded wiith a Scott Hale try.
Cooke scored for 10-4 before Anthony Thackeray bulldozed his way through and Tom Hemingway kicked the extras to bring the tie level.
Sanderson cancelled out Kieran Hyde’s penalty for 12-12, before Greg Scott scored the final try of the game.
A Hyde conversion and penalty claimed maximum points for the Rams.
