The 26-year-old front rower has inked a one-year deal at the club.
“I really am looking forward to the challenge of playing in Super League and experiencing a different style of play with a new team,” Dodds told Wire’s official website.
“Warrington is a club that is competing at the top both on and off the field and I look forward to being part of that next season.
“My two assistant coaches here at the Broncos, Allan Langer and Kevin Walters, only have great words to say about Warrington and their time at the club so I can’t wait to get over there and start experiencing a different culture and lifestyle in England.”
Warrington head of coaching Tony Smith is very pleased that a player of such quality will be at the Wolves next year.
“We are delighted with the signing of Mitchell,” he said.
“He’s played a big part in the Broncos’ team this year. He’s played most of his games off the bench and they are in there fighting for a title as we speak.
“We need that sort of experience coming into our squad. He is a no-nonsense hard-hitting prop forward who is probably best known for his defensive efforts; we need to strengthen in that area as it’s probably not been our strongest year defensively.
“He’s got some of the experience needed to tighten us up down the middle. He’s a terrific young player who is keen to have a new experience and bring his wares to Super League.”
