Hull FC were cut to pieces in embarrassing fashion by a red-hot Widnes Vikings as the Super League table-toppers scored 46 unanswered points after falling behind early on.
The Airlie Birds were given a harsh lesson after a controversial decision by the video referee ruled out what looked a legitimate try for Sika Manu which led to a capitulation that is not generally related to this proud side.
Coach Lee Radford restored Frank Pritchard to his match day squad and gave him his first start after he missed the narrow defeat against Wigan Warriors, Liam Watts dropped to the bench to be replaced by in-form Josh Bowden at prop.
Jordan Abdull was drafted in to replace the injured Leon Pryce and Mark Minichiello dropped to the bench having started the first four games of the season for the black and white’s.
The Vikings had an early blow when Chris Bridge had to leave the pitch with a shoulder problem after a challenge with Pritchard after two minutes.
The Airlie Birds drew first blood after six and a half minutes as Pritchard crashed through the Widnes defensive line to score his first try for his new club after a bullocking run by Scott Taylor set up the position, Marc Sneyd added the conversion for a six point lead.
Three minutes later Fetuli Talanoa was denied a try by the video referee as he dropped the ball diving for the corner.
The video referee was called into action after Abdull launched a high kick and, after Jack Logan challenged Stefan Marsh in the air the Vikings player lost the ball and Sika Manu went over, however controversially the extra official Phil Bentham ruled out the try.
The league leaders then went straight to the other end and Joe Mellor got on the end of a fast move to touchdown, Rhys Hanbury brought the scores level in the 16th minute.
Widnes then turned the match on its head after Marsh made an interception and break and, from that position an attacking kick from Kevin Brown leading try scorer Corey Thompson crossed to put the Vikings undeservedly ahead after 20 minutes, Hanbury was wide with the touchline conversion attempt.
Hull were denied another try by the video referee after 25 minutes after Manu knocked on in front of the line before crashing over.
Thompson then added his second try of the game in the 28th minute after a wide kick from Mellor saw Talanoa again out of position to allow his opposite number to gather and touchdown far too easily, Hanbury again was wide with the conversion to leave the home side with an eight point lead.
The Vikings then stretched their lead after another wide kick from Brown presented them with another opportunity for marsh to cross the whitewash after 32 minutes, Hanbury was wide with another conversion attempt.
Widnes then got a controversial try after Liam Watts appeared to pinch the ball in a one-on-one tackle but referee Richard Silverwood maintained it was still Widnes ball and subsequently Hanbury got on the end of a pass and then converted his own try to give them an 18 point lead at the break.
Brown extended the Vikings lead after 46 minutes after a mistake by Jamie Shaul from a high kick presented them with a scrum near the Hull line and the Widnes captain side stepped through the Airlie Birds defence, Hanbury took them to the 30 point mark with the conversion.
The Vikings were then given another controversial try after Marsh was awarded a second try by the video referee despite appearing to drop the ball after 52 minutes, Hanbury made it a 30 point lead with the conversion.
The Vikings hit the 40 mark as Matt Whitley crossed under the posts just short of the hour, Hanbury added the extras to make it a 36 point lead.
Marsh then got his hat-trick after a move from one side to the other and back again, Hanbury missed the conversion to leave the score at 46-6.
The Vikings were given more possession and territory with a scrum 10 meters from the visitors line despite the fact that Chris Houston appeared to knock the ball onto Danny Washbrook but a penalty allowed Hull to clear their lines.
Hull kept Widnes out for the rest of the game to at least avoid the ignominy of conceding a half century of points after their worst display for some time.
