Leigh are just one game away from the Championship Grand Final at Headingley after coming from behind to defeat Doncaster at the Sports Village.
But their coach Paul Rowley admited they needed “a kick up the backside” after they trailed 14-6 with 10 minutes of the first half remaining.
Centurions recovered to lead 24-14 by the break to the delight of their coach Paul Rowley.
“I thought we were excellent for some stages,” said Rowley. “We did it tough and were probably our own worst enemies, especially in the first half.
“We gave away a lot of penalties but at half-time we sorted out a few things and I knew if we got a good share of possession we would score.
“Doncaster have got some good players and we were inviting them to build pressure so we needed a kick up the backside before half-time.
“But to win with such a scoreline in a play-off is a tremendous result.”
Tom Armstrong, Michael Platt and Ryan Brierley all scored two tries each for Leigh who now have a week off before their play-off semi final which will again by played at the Sports Village.
