Hull KR coach Justin Morgan was happy to take advantage of a controversial decision by referee Steve Ganson in his side's derby win over Hull on Sunday.

Hull had edged 17-16 ahead in a tense engage Super League encounter at the Millennium Magic event in Cardiff with a 74th-minute drop goal.

But Tommy Lee was adjudged to have knocked on from the subsequent restart and Rovers took full advantage with Jake Webster crossing to snatch a 22-17 win.

It was the second year in succession Ganson had been at the centre of refereeing controversy at the showpiece event, the same official having been in charge of the contentious clash between Leeds and Bradford last season.

Morgan said: "It is what the referee says. We have been on the end of good and bad calls all season.

"Everyone is on the end of bad calls. It's what's gone in the little box at the end of the day and it's us that got two points. That's all that matters."

The scores were locked at 10-10 at half-time and at 16-16 for most of the second half.

Rovers enjoyed a sustained spell of pressure but could not force their way over the line and it was Hull who looked to have decisively broken the deadlock when Dykes struck.

Morgan added: "I think you saw the body language of the Hull team, they got a huge kick out of it.

"Even though we sucked a lot of petrol out of the tank they lifted their chins off the floor and defended five sets of six.

"To our players' credit they showed a huge amount of courage and determination.

"We had plenty of ball when we were looking for a few better decisions with ball in hand but we kept our composure for the entire 80 minutes."

Gareth Raynor claimed two tries for Hull and Danny Washbrook also touched down while Rovers scores came from Peter Fox, Daniel Fitzhenry and Chev Walker.

Hull coach Peter Sharp felt his side had been hard done by.

"It was massive," he said of Ganson's late decision. "There is a lot of money and a lot of things at stake for a lot of clubs and we come up with decisions like that. We have got to do better than that."

The defeat leaves Hull 10th in the table with just nine points from their 13 games.

But Sharp added: "I think we showed signs we are on the mend and improving. I think we can build some momentum."

Morgan said he would be dedicating his side's victory to James Webster, the former Rovers captain who was released last week.

Morgan took the decision to let Webster go after the Australian scrum-half was ruled out for the rest of the season.

"James Webster has been an integral part of this club for many years," Morgan said.

"We have massively struggled in the past without him and I dedicate this victory to Webbo and his contribution to this club.

"It was a really difficult decision. Sentiment comes into your thought process but at the same time my remit is to do what is best for the club."
