ROB Butler has left Warrington Wolves with immediate effect.

The prop forward’s anticipated move to Super League rivals Wakefield Trinity on a permanent deal has been confirmed, with Butler signing on at Belle Vue until the end of next season.

The Wire are open to bringing in mid-season reinforcements and the departure of Butler, whose sole first-team appearance this year came in the 38-22 loss to his new club in March, opens up salary cap space should that opportunity arise.

Having joined from London Broncos ahead of the 2021 season, the 23-year-old has made just six appearances for the Wire first team.

The England Knights international spent time on loan with Leigh Centurions during last year and 2022 has seen him feature mainly for the club’s reserve team, starting three of their four games so far.

“I’m really excited to be joining Wakefield," he told Trinity's official website.

"It was great this morning to come to training and meet everyone. Everyone has been super-friendly, and I couldn’t have asked for more on my first day.

“I’m now looking forward to kicking on at Wakefield, finding some form and playing regular rugby.

"I’ve played with a few of the boys at London and Warrington and they’re all good people so it’s nice to see some familiar faces too.

“I know from playing against Wakefield that they are a real tough team to play against.

"Hopefully I can add something to the squad and help us get back to the form showed a few weeks ago.”
