SEAN O’DRISCOLL described his team’s performance as “a disgrace” as Rovers slid closer to the drop zone.
Doncaster created plenty of chances going forward but their defensive frailties were exposed by a Hull side for whom goals have been in short supply at the KC Stadium.
The defeat left Rovers hovering just five points above the bottom three - and had O’Driscoll fuming.
O’Driscoll said: “I thought we were a disgrace.
“For a team that’s fighting for its life, I thought we played like there was nothing on the game.
“We’ve scored something like four goals in the last ten games.
“So if we think we can go to any ground in the Championship and outscore teams then we’re deluding ourselves.”
O’Driscoll was unhappy at the openness of his side during Tuesday’s night’s 1-1 draw with Preston.
And he cast a frustrated figure as he watched his team put in almost an identical display against the Tigers, sweeping forward with gusto but continuing to look incredibly brittle at the back.
It took just nine minutes for the hosts to break the deadlock when Richard Garcia was left with a simple tap-in after a mistake by Shelton Martis.
Franck Moussa levelled when he expertly drilled home after Simon Gillett’s shot was tipped onto the post by Vito Mannone.
But Hull were back in front midway through the first half when Matty Fryatt converted from the penalty spot after Martis’ shove on James Chester.
Hull’s third, when Fryatt nodded home unmarked five minutes after the restart, left Rovers with a mountain to climb.
They responded well and James Hayter saw his close range effort somehow blocked by Mannone, Ryan Mason’s curler was then tipped away by the Arsenal loanee and Moussa headed a gilt-edged chance over the bar.
But for all of Doncaster’s flair and creativity they were undone by sloppy defending, leaving O’Driscoll riled and setting up a hugely important clash with relegation rivals Crystal Palace at the Keepmoat Stadium on Good Friday.
