Mason injury adds to Castleford's pain

Huddersfield's prop, Keith Mason, could be facing a lengthy spell on the sidelines after suffering a groin injury in the defeat by Castleford that continued their depressing form since their coach, Nathan Brown, announced his departure.

"He's in a lot of pain. There's definitely something wrong with him," said Brown. "If Keith needs a few weeks off, he needs a few weeks off."

That blow is eased by the expected return of Eorl Crabtree for Sunday's fixture against Crusaders.

Brown declined to comment on suggestions that he has changed his mind about returning to Australia at the end of this season and now wants to stay at Huddersfield.

The club also say they are in the dark about any change of plan. They are still expected to appoint Brown's assistant, Paul Anderson, later this year.

Castleford have agreed a two-year contract extension, until the end of 2013, with their highly-rated wing/full-back, Richard Owen. Cas have moved to secure Owen despite him being out for the rest of the year with a broken leg. The Tigers now turn their attention to trying to retain the England centre, Michael Shenton, a target for St Helens.

The Wigan forward, Andy Coley, will face a charge of making a reckless high tackle on the Catalan Dragons' Jamal Fakir at today's disciplinary hearing.

Hull have signed 17-year-old Reece Lyne, until the end of 2013. Lyne has played just one Super League match, but is regarded as one of the game's hottest prospects.

The Hull KR centre, Michael Ratu, will miss the rest of the season with a damaged shoulder.
