Paul Dickov urged his side to keep on believing after they slumped to a disappointing home defeat to Leyton Orient.
Goals from Jay Simpson and Darius Henderson condemned Doncaster to their sixth league reverse of the season.
The defeat leaves Rovers 17th in League One and just two points better off than bottom club Scunthorpe United.
But Dickov says now is not the time to panic and urged players and fans alike not to lose the faith.
“Things can turn around in football very quickly,” said Dickov.
“We have to keep on going and we have to keep on believing in ourselves.
“We were a lot better than we were on Saturday [at Fleetwood]. The was the biggest positive.
“I’m very disappointed with the result but I asked for more effort and I got that.
“We just didn’t take our chances.”
Dickov and his bench were furious that referee Chris Sarginson failed to award Rovers a penalty for handball, following an error from Orient’s former Rovers goalkeeper Gary Woods, with the score at 0-1.
“It was a blatant hand ball,” said Dickov.
“Everyone in the ground has seen it and it came at such a crucial time in the game.”
On Henderson’s sensational second goal, Rovers’ boss added: “It was a fantastic strike, but we should have dealt with it before then.”
Dickov will now step up his attempts to bolster his squad before Saturday’s visit of high flying MK Dons to the Keepmoat Stadium.
