Hull KR v Crusaders: Teams

Willie Mason will make his eagerly-awaited Super League debut on Sunday when Hull KR welcome Celtic Crusaders to Craven Park.

Powerful Australian forward Mason has finally sealed his move to Rovers and Crusaders know they will be in for an almighty battle once he gets into the field.

Justin Morgan has Mason to call on, but is without skipper Michael Vella who is out for six weeks with a knee injury.

Prop Rhys Lovegrove will make his first appearance of the season to replace Vella, while Joel Clinton remains on the sidelines after being dropped last week.

Hooker Lloyd White is back in Iestyn Harris' Crusaders squad for the first time this year, as he comes in for Adam Peek who is nursing a hamstring strain.

Winger Rhys Williams keeps his place after his initial month's loan from Warrington was extended on a week-to-week basis.

Players back

"As we start to get players back we are going to be extremely difficult to beat," Harris said. "We've had a couple of substandard performances - at Harlequins where we could have snatched it at the end, and Bradford for because of some big individual errors.

"The performance was a lot higher in intensity against Hull, we weren't a million miles away. I know the scoreline doesn't suggest that but we are improving as the season progresses and sooner rather than later we are going to catch somebody."

Harris is not fearing the introduction of Mason, saying it could hinder Hull KR more than it will the visiting Welsh side.

"It is going to interrupt them more than it will us," he added. "We're going there with a plan and a structure of how we think we can win the game and hopefully we will get it right

"It is going to be an extremely high intensity game on Sunday. It is a tough ground to go to, they are very, very good at home. I know they had a blip against Catalan who caught them off guard but historically this club has struggled there.

"We will try to lift our intensity and our performance and try and make sure we are very clinical individually and collectively, and do everything we can to upset them because we are expecting a full house and a caldron atmosphere. It is certainly one you want to play in."

Hull KR: Cockayne, Galea, Green, Fisher, Newton, Hall, Hodgson, Netherton, Webster, Welham, Colbon, Watts, Fox, Lovegrove, Latus, Murrell, Wheeldon, Briscoe, Mason.
