Notts County boss Keith Curle blamed "juvenile defending" for his side's 2-0 home defeat to Doncaster.
After a dismal first half, quickfire goals from Paul Keegan and substitute Chris Brown in the second period gave Rovers all three points.
Both sides had to make changes at half-time after a sickness bug struck a player on opposing sides, with centre-half Dean Leacock the unlucky man for Notts. And Curle felt his side did not deal well with the enforced change.
"We had a little bit of disruption at half-time as 20 seconds before we were going out Dean Leacock started throwing up and was unable to take the pitch," said Curle. "Ideally you want the whole break to know what's going on but when it is just before you go out you have to make a split decision straight away.
"It meant a little bit of a regroup and a reshuffle but there was still enough experience out there to defend the edge of our box properly. Both goals should have been stopped easily - it was juvenile defending.
"We gave the points away too easily and we've done that too often of late at home. We will turn it around though and we will change it. We want to entertain our public but we want to win football matches first."
