Andrew Fifita could see out his career with Cronulla Sharks after signing a new long-term deal with the NRL premiers.
The Australia front-rower was already contracted for next season and has now agreed to extend his stay until the end of the 2022 campaign.
Fifita was man of the match in New South Wales Blues' victory over Queensland Maroons in the opening game of this year's State of Origin series and played a key role for Cronulla in their 2016 NRL triumph, scoring the winning try in the Grand Final against Melbourne Storm.
Shane Flanagan expressed his delight at the 27-year-old's decision to commit to the club.
"We've all seen the growth in Andrew off the field and his football has gone to a new level as well over the last couple of seasons," said Sharks coach Flanagan.
"He is a match-winner, as we saw in the Grand Final and then again in the first Origin game and to have him here at the club for a further five years is very exciting."
Fifita has played 114 games for the Sharks since his move from Wests Tigers in 2012.
