Australian forward Trent Waterhouse is to leave Warrington at the end of the season, which could spell the end of the 33-year-olds rugby league career.

Waterhouse, who won two caps for the Kangaroos, has made 78 appearances for Warrington since joining them from Penrith Panthers three years ago and was in their Challenge Cup-winning team in 2012.

Waterhouse is expected to hang up his boots, along with hooker Michael Monaghan, who announced his decision to retire earlier this year.

Warrington are also parting company with first team coaches Willie Poching and Richard Marshall, as well as conditioner Chris Baron, sports scientist Andy Holleyhead, soft tissue therapist Amanda Turner and joint Under-19s community coach Danny Fullerton.

Warrington’s head of coaching and rugby Tony Smith, who has appointed former Wakefield and Hull boss Richard Agar as his new right-hand man for next season, 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.
