An attempt by Doncaster's Harry Forrester to pass the ball back to Bury following a throw-in in stoppage time ended in a freak goal when it bounced over visiting keeper Christian Walton, who had originally kicked the ball into touch following an injury yesterday.
But with time ticking away at the end of the match, Doncaster manager Paul Dickov told his players to allow Leon Clarke to stroll half the length of the pitch unchallenged from the kick-off and score the equaliser, which meant the match finished 1-1.
Bury manager David Flitcroft hailed his opposite number.
"I've got the ultimate respect for Paul Dickov. He tried to get the referee to award a foul throw initially but then he's allowed us to score from the restart.
"Paul put football into a good place with his sportsmanship today because if you lose morality the game has no substance for me.
