Gary Thornton’s harsh introduction to life at Doncaster continued as they were pushed aside by London Broncos.
Responding to a total demolition at Bradford the previous week, the Dons battled superbly for much of the game but were ruthlessly taken apart with a three-try burst midway through the second half.
The Dons, who have lost all 17 games this season, had real energy and intent from the first whistle, spending the opening 10 minutes camped in the visitors’ half as they forced several errors.
But their failure to turn pressure into points proved their undoing.
London scored with their first real foray into Dons territory on nine minutes when the impressive Ben Hellewell crossed the line. There was better from Doncaster seven minutes later as they cut through London to draw level, Liam Welham scoring from Paul Mennell’s kick.
After competing well for much of the half, Doncaster were scythed open when on-loan Leeds man Elliot Minichella weaved through and Wes Naiqama added the first of four conversions.
The tight nature of the clash continued after the break, reflected by Naiqama’s decision to go for the posts from a penalty.
But the Dons’ challenge was ruthlessly ended as London ran in three tries in an eight-minute spell to put the game to bed. Hellewell scored twice to complete his hat-trick, sandwiching a try from Rhys Williams.
