The Bulls' winless league run stretched to six games after a thumping 46-18 defeat at fellow strugglers Hull KR.

In an encounter littered with errors, Bradford went ahead within three minutes, Kyle Briggs touching down when Ben Jeffries' kick was knocked down by Ian Sibbit.

The hosts levelled when Michael Dobson sent in Kris Welham and then went ahead when the same combination worked again.

Blake Green scored a decent individual effort before Gareth Raynor responded for the Bulls, off a pass from Jeffries.

But Hull were allowed to score twice more before the break, Jake Webster pouncing on Green's grubber before Dobson touched down from his own kick.

The hosts were first to strike after the interval, Liam Watts scoring off the pass from Peter Fox, before Bradford responded through Andy Lynch.

Kris Welham completed his hat-trick just before the hour mark and Fox heaped on further misery three minutes from time.
