CHRIS Riley and Trent Waterhouse will join Michael Monaghan in leaving Warrington Wolves at the end of the season.

Four younger members of Wolves’ first-team squad will also be moving on, departing along with coaches Willie Poching, Richard Marshall, Chris Baron, Danny Fullerton and two more members of Tony Smith’s backroom team.

Winger Riley, aged 26, lost his place to Rhys Evans after Round One of Super League this year and has since been on loan with Wakefield Trinity Wildcats.

But his permanent departure, with a year still to run on his contract, will be a surprise to many.

The England Knights international, who can also cover at full back, had been first-choice wing partner to Ryan Atkins since Matt King’s departure at the end of 2011, scoring 48 tries during 2012 and 2013 campaigns.

He was on the left flank for all three Challenge Cup successes at Wembley in 2009, 2010 and 2012, the Grand Final losses in 2012 and 2013 while also figuring in the squad that won the League Leaders’ Shield in 2011.

Since his debut in 2005, he has made 180 appearances in primrose and blue and crossed for 120 tries, the third most by a Warrington-born player.

Riley came through the ranks at the club after having played his junior rugby with Woolston Rovers.

Meanwhile, powerful Australian back rower Waterhouse will head out of The Halliwell Jones Stadium at the end of a three-year deal that brought him to England from NRL club Penrith Panthers.

Speculation had been growing that the former Test international would not be around next season but up until last week’s Wolves weekly press conference head of coaching and rugby Tony Smith said a decision had not been made on Waterhouse’s future.

Before his move to Wolves, as a replacement for Louis Anderson, he played twice for Australia in the 2009 Four Nations Tournament and five times for New South Wales in State of Origin matches. Further representative honours came over here with the Exiles.

He has made 78 appearances for Warrington so far, including the 2012 Challenge Cup Final victory over Leeds Rhinos at Wembley and the Grand Final loss to the same opposition at Old Trafford in 2012.

Also on the way out of the club are first-team squad members Danny Bridge, Jordan Burke, James Saltonstall and Gavin Bennion.

Bridge, the younger brother of half back Chris, made three appearances in the first team last year and gained honours with Ireland in the Rugby League World Cup.

The 21-year-old, who is out of contract at the end of November, started the season on loan with Bradford Bulls but has not been able to nail down a primrose and blue shirt in 2014.

Former Rylands amateur Burke, aged 22, whose one and only first-team appearance came at full back in a Challenge Cup fourth-round tie at Keighley Cougars in 2012, has spent a season-long loan in the Championship with Sheffield Eagles this year.

Saltonstall, a member of Italy’s squad in the Rugby League World Cup last winter who played on the wing in the shock warm-up defeat of Egland, made it into one of Smith’s 19-man squad selections last year but has never had the nod for a start.

The full back or winger, who was contracted with Wolves until the end of 2015, is currently on loan with Championship One table toppers York City Knights, having also spent some time with Bradford Bulls earlier in the year.

Prop forward Bennion has been on a season-long loan with Featherstone Rovers.

Like Saltonstall, he was named in Wolves’ 19-man squad for the visit of Salford City Reds last year but did not make the cut and has not figured since.

As previously reported, joint skipper Michael Monaghan is retiring upon completion of the 2014 season.

First-team coach Willie Poching will be moving to Hull Kingston Rovers as right-hand man to their new head coach, Chris Chester.

Fellow first-team coach Richard Marshall, strength and conditioner Chris Baron, sports scientist Andy Holleyhead, soft tissue therapist Amanda Turner and joint U19s community coach Danny Fullerton will all be saying their goodbyes at the end of the season too.

The only new staff recruit announced so far is Richard Agar, the former Hull and Wakefield boss, who will be joining as Smith’s new assistant.

Smith said: "All of these players and coaches have been a pleasure to work with over their time at the club and have contributed to our continuing success.

“We’ve all built up a great relationship and anybody who has been part of the Warrington family will always be welcomed back.

“We wish them all well for the future and look forward to our paths crossing in the future.”
