KNIGHTS’ five game unbeaten run came to a shuddering halt at home to Nottingham.
Brett Davey made five changes from the side that drew 18-18 at Bedford Blues last weekend.
But his side’s performance was unrecognisable from the battling display at Bedford as indiscipline and poor defending cost Doncaster dearly.
After a positive start, which saw Jack Farivarz driven over by the home pack on nine minutes, Knights spent the majority of the first half on the back foot and conceded a succession of penalties.
Kieran Hallett kicked four superb three-pointers, while Edward Mama scored an all-too-easy try shortly after Farivarz went over.
The visitors were in the boss seat and a disappointing half went from bad to worse when full back David McIlwaine gifted the ball to James Alridge ten yards out for Nottingham’s second try, which the reliable Hallett converted.
Second half tries from Latu Makaafi and Michael Keating raised hopes of a comeback - or at least a bonus point - but Nottingham had the final say when Joe Duffey was driven over to complete an emphatic win for the visitors.
