Alex Brown scored a hat-trick inside the opening 40 minutes for the visitors as they ran in a total of eight tries.

Kris Welham touched down twice and Craig Eden was also on the scoresheet, while Craig Gower went over for the hosts during a lively first half.

Michael Dobson kicked over an additional six points for Hull as they led 30-6 at the break.

However, the Broncos scored two quick tries in the opening 13 minutes of the second half through Kieran Dixon and Chris Bailey.

Michael Witt added six points with the boot as the home side cut the deficit to 12 points.

Hull then moved out of sight on the hour as Liam Salter touched down before Cory Paterson stretched the advantage with a try of his own seven minutes later.

There was some late cheer for the Broncos when Daniel Sarginson went over on 76 minutes, but it was only a consolation.
