ANOTHER superb second half performance saw the Knights overwhelm relegated Leeds Carnegie and sweep to their third straight RFU Championship win.
Again it was the opposition who started the strongest with Jacob Rowan latching onto a loose ball and darting down the blindside for the opening try on 17 minutes, converted by Tommy Bell.
This appeared to jolt the Knights into action and they won possession inside the Leeds 22, with Tom Davies eventually crashing over.
Leeds increased their lead with two penalties from Bell before the half hour.
Quick reactions to receiving a penalty on 30 metres saw the Knights score again with Oli Goss released following a quick tap to score in the corner.
Tom Luke levelled the scores three minutes before the break with a penalty and the Knights soon took the lead with David McIlwaine slotting over a penalty from his own half.
Leeds drew level almost immediately after the break with Bell landing a penalty.
But from here the Knights were virtually camped on the Carnegie line.
Superb defending from the hosts pushed the Knights back and they gained good territory only for a poor lineout to put Doncaster back on the front foot.
The Knights broke and McIlwaine sliced through the defence, dodging desperate tackling to go over with Mike Whitehead adding the conversion.
Doncaster sealed the bonus point with the final play of the game.
Whitehead charged over between the posts and converted his own try to secure a 30-16 win.
