Why Adrian Lam has a "selection migraine"

Ben Flower and George Burgess are back in the mix after being sidelined by a combination of suspension and minor injuries.

They are set to play in Saturday’s showdown against Castleford - giving Lam a big call to make on who to leave out.

Mitch Clark, recruited from Castleford for this season, has already dropped out of provisional 21-man squad but Ethan Havard, Liam Byrne, Joe Bullock and utility forward Morgan Smithies are in the frame.

And competition for places will be dialed up even more next week when No.13 Sean O’Loughlin is set to be fit and Oli Patington returns from suspension.

Lam said: “It’s not giving me a headache, it’s giving me a migraine!

“But that’s exciting and as a coach it’s exactly what you want.”

Tony Clubb is sidelined by a neck injury which Lam expects to rule him out long-term, though he is still awaiting confirmation.

Thomas Leuluai is expected to replace Harry Smith at halfback.
