Castleford Tigers have announced the signing of prop Keith Mason on a one year-deal.

Tigers head coach Ian Millward said, “I was in search of an experienced forward who could offer a presence both in training and on the field and Keith fits that bill. Having previously coached him at St Helens, I know him to have one of the best work ethics in the game; he commands respect from his peers and will no doubt have a positive impact on the team.

“I am confident that Keith still has some of his best years ahead of him which should also create some healthy competition between the forwards as we gear up for next season. He starts with immediate effect and will join the squad in training tomorrow (Thursday).”

Mason is Millward’s eighth signing for the 2013 season, joining Lee Gilmour, Michael Shenton, Jake Webster, Jamie Ellis, Jordan Tansey, Justin Carney and Weller Hauraki
