Josh Mansour celebrated his new contract with a try as Penrith Panthers moved into the NRL's top eight with a 28-26 victory over the struggling South Sydney Rabbitohs.
The Panthers announced a new two-year deal for New South Wales winger Mansour on Friday, just before their round 16 fixture at Pepper Stadium.
Mansour duly claimed his 40th four-pointer for the club, while 18-year-old playmaker Nathan Cleary - the son of former Penrith coach Ivan - was also among the try-scorers and kicked four conversions in a hugely impressive showing.
South Sydney, who handed a debut to new arrival Joe Burgess, have now lost four games in a row and appear increasingly likely to miss out on the play-offs.
Converted tries from Kyle Turner and Greg Inglis, either side of a Cody Walker penalty, ensured Souths led 14-10 early in the second half, despite Dallin Watene-Zelezniak and Mansour crossing for the Panthers.
However, the hosts duly seized command as Leilani Latu, Cleary and former Rabbitohs forward Chris Grevsmuhl all touched down.
Sam Burgess scored twice in the final six minutes, but the Bunnies ran out of time in their bid to complete a remarkable late fightback.
Panthers executive general manager Phil Gould had earlier hailed the retention of Mansour, stating: "It is wonderful to have Josh on board for another two seasons and to be honest I hope he's here for the rest of his playing career."
