Full-back Richard Mathers, utility back Cameron Phelps and back-row forwards Harrison Hansen and Lee Mossop have all signed contract extensions.

In addition, centre George Carmont has triggered the second year of his conditional two-year contract.

Chairman Ian Lenagan said: "We are pleased we have secured the futures of these five players all of whom are important members of the future Wigan squad."

Mathers signed for the Warriors from Gold Coast Titans in November 2007 on a three-year deal, with seasons 2009 and 2010 subject to his completing a certain number of games.

Although this target was not met in 2008, chairman Ian Lenagan and coach Brian Noble both believe that Mathers is deserving of the contract extension for 2009 plus a Wigan option for 2010.

Phelps arrived at the end of May for the remainder of 2008 and has now signed for 2009 with a further option for 2010 in Wigan's favour.

Mossop, who made his first-team debut this year scoring a try in the Challenge Cup tie against SM Pia XIII, has agreed terms for 2009 and 2010 with a third year option for Wigan.

Hansen has also signed a further two-year contract extension committing to Wigan until the end of 2011.

The fifth player to commit his future to the club is Carmont who originally agreed a two-year deal with the Warriors, the second year of which was subject to a certain number of appearances. George has easily reached this level having played in every game so far this season.

Head Coach Brian Noble added: "I am pleased that the future of these five players has been secured providing important continuity within a developing Wigan squad - important for the individuals, for me and for the club as we plan ahead for 2009 and beyond."
