Canterbury prop Tevita Pangai Jr has decided to end his rugby league career at the end of the season to take up boxing.

The 27-year-old, contracted for 2024 on an estimated $750,000-a-year contract, has informed the Bulldogs of his desire to focus on family and fighting.

The Tongan international will play out the remainder of the season before swapping his boots for gloves.

Pangai has twice fought professionally and holds a 2-0 record, first defeating Gerico Cecil by technical knockout in December 2021 and then knocking out Jerry Tupai last December.

"We would like to thank Tevita for his contribution to the club," said Bulldogs football boss Phil Gould.

"We are well aware of his talent as an athlete and are fully supportive of his decision to pursue another sport at the season's end.

"We wish him and his family all the best for the future."

The rugby league retirement continues a whirlwind year for Pangai, who was selected to make a surprise New South Wales debut in the State of Origin series opener.

He was dropped for the second game of the series and has since struggled for consistent form with the 15th-placed Bulldogs.

At his best, Pangai was one of the most damaging forwards in the game.
