The Panthers recovered from concerning back-to-back defeats to stun the Warriors last start, while the Sharks will be feeling refreshed after having the bye.
With a number of players from both squads potentially backing up from Origin III on Wednesday night at Suncorp Stadium, this looms as the match of the round.
The home side will also be gunning for revenge after Shane Flanagan's men won a quality round seven encounter 26-22 at Southern Cross Group Stadium back in April.
Key match up: Trent Merrin and Paul Gallen don't play the same position these days, but they are both classic interchangeable forwards who can slot in anywhere in the pack, except of course at hooker. The former NSW Origin teammates are known for not taking a backward step and there will be plenty of feeling every time they lock horns.
Match: Panthers v Sharks
Round 18 -
Venue: Panthers Stadium
- LIVE PASS
For the Panthers to win: Dominate the forward battle. The Cronulla pack are fearsome on their day, with the likes of Paul Gallen and Andrew Fifita always keen to lay an early platform in the engine room. James Fisher-Harris, James Tamouand Trent Merrin need to match their enthusiasm and ferocity from the opening set of six.
For the Sharks to win: Provide centre Jesse Ramien with plenty of ball. The youngster has been sensational all year, making tackle busts for fun. He has also scored nine tries in 13 appearances this season.
Panthers stat attack: James Maloney has engaged the line 65 times, more than anyone else in the competition. Cowboys halfback Johnathan Thurston (62) and Tigers playmaker Luke Brooks (59) are the next best after 17 rounds.
Sharks stat attack: Prop Andrew Fifita (53) is the competition yardstick for offloads, fractionally ahead of Sea Eagles enforcer Marty Taupau (52). Matt Moylan (14) also has the most line-break assists.
And another thing: It may only be July, but this game has a semi-final feel about it. Both teams have genuine title aspirations, and it could be a nail-biter.

The Panthers will start 1-17 after Liam Martin, Kaide Ellis and Tyrone Peachey were omitted an hour before kick-off.

Ava Seumanufagai and Kyle Flanagan were the two players omitted 24 hours out from kick-off.

Petero Civoniceva's prediction: Penrith will be buoyed by their impressive win over the Warriors last Friday where a number of their young guys stood up and announced themselves as future NRL stars. It should be an absolute cracker, with Cronulla fresh after the bye last weekend and Matt Moylan returning to his old stomping ground.
