Warrington scrum-half Richie Myler fractures cheekbone
Warrington scrum-half Richie Myler is facing up to two months out after suffering a fractured cheekbone in Friday's 60-0 victory over Salford.
The 20-year-old England international, an ever-present for the Super League leaders this season, will see a specialist on Monday.
Myler scored in the 10-try thrashing of Salford but was later forced off with the injury.
Hooker Michael Monaghan could switch to scrum-half for Monday's visit of Hull.
Myler was signed for Warrington on a four-year deal by Tony Smith from Salford for a six-figure fee in July 2009, making him the most expensive teenage signing in rugby league history.
He had a comparatively disappointing first season with the Wolves, being left out of their Challenge Cup-winning team at Wembley last August.
But he has responded well this season, scoring nine Super League tries in 11 games - a tally bettered by only one man, Hull KR centre Kris Welham.
