ROVERS laid out the red carpet for the Royals - as a shambolic defensive display gifted Reading the points.
Matt Kilgallon went straight into the side following his loan move from Sunderland and hardly put a foot wrong.
But he could only watch in horror as Rovers' defence parted like the Red Sea and allowed Shane Long the freedom of the Keepmoat Stadium to slot the visitors in front on the half hour.
Doncaster had started brightly and went close when Billy Sharp just failed to direct Kilgallon's cross on target.
But Long's effortless goal knocked the stuffing out of the hosts and, despite briefly threatening after the restart, worse was to follow.
Neil Sullivan went walkabout and allowed Jimmy Kebe to casually lob him midway through the second period after the winger latched onto Mikele Leigertwood's long through ball.
Rovers then had ample opportunity to get rid of the danger before George Friend's clearance deflected in off Jobi McAnuff for Reading's third - rounding off a thoroughly forgettable afternoon and an uncharacteristically abject Doncaster performance.
