Tries by Chad Randall, Will Sharp, Dave Howell, Henry Paul and two penalties from Rob Purdham gave Quins a 28-0 half-time lead, from which Rovers never recovered, despite a late fightback led by Michael Dobson.

On his side's chances of making the play-offs, Morgan said: "Realistically when you toss up that sort of performance, you're not going to do much when you get there anyway, never mind winning games to get there. I'm not worried about that, I'm worried about how poor we were."

He added: "It was the lack of effort that worried me most."

Asked what had gone wrong Morgan replied: "How long have you got? It's easier to talk about what went right - not much.

"It's difficult to put your finger on what went wrong and a week is a very long time in the game.

"We didn't turn up to play in the first half. We fell too far behind and we can't claw that back.

"I sound like a broken record at times. I've said this plenty of times this season about conceding that many points and expecting to win games."

His opposite number, Brian McDermott, was delighted with his side's display and even went as far as suggesting it was a contender for the London club's away performance of the campaign.

"It rivals Hull up here as our best performance on the road this season," he said. "Things just seemed to work and I thought we just looked in control."
