THE NRMA Insurance Broncos have added some size and experience to their middle forward rotation with a surprise signing this morning.

Premiership-winning prop Sam Tagataese has joined the Broncos on a one-year deal in a move that will add depth to the NRL squad.

He trained with his new teammates for the first time this morning.

Tagataese has played with the Storm, Titans and Sharks, winning the 2016 Grand Final with Cronulla.

He has 168 games of NRL experience, and at 193cms and 110kg will give the Broncos another weapon in the middle after losing both Adam Blair and Herman Ese’ese in the off-season.

Samoan international Tagataese said he was excited to join the Broncos, especially as it will be his first time working under Wayne Bennett.

"I am definitely excited especially as my partner is from Brisbane, and when I first moved to Australia I lived in Brisbane," he said.

"I actually haven't (met Bennett before) but I am definitely looking forward to it.

"I have heard so many good things about him, and just look at his record.

"And as my father-in-law said, he is a master coach.

"I am looking to getting the best out of myself at this point of my career and being coached by a great coach."

The Broncos have also confirmed they released David Mead yesterday to take up a three-year deal with the Catalans Dragons in the English Super League.
