The Panthers took the Broncos' best punch last week, coming from behind to carve out a 25-12 win - their 15th of the season - and remain firmly on course for the minor premiership.
Their only loss in 2020 was at the hands of the Eels back in round five, so payback will be high on the agenda on Friday night at Panthers Stadium.
The old saying goes that teams on long win streaks are better off losing a game before the finals. Only time will tell in the case of the Panthers.
Parramatta got their premiership campaign back on track with last week's convincing win over an in-form Warriors outfit, but we'll get a much clearer picture of where the Eels are truly at on Friday.
Match: Panthers v Eels
Round 18 -
Venue: Panthers Stadium, Penrith
Panthers: Penrith will start 1-17 after Mitch Kenny and Kurt Capewell were omitted an hour before kick-off. Lock Isaah Yeo will return from a head knock with James Fisher-Harris returning to prop and Moses Leota to the bench.
Matt Burton and Charlie Staines were omitted 24 hours before kick-off.
The Panthers are aiming to become the third team in the NRL era to win 13 in a row in one season.
Eels: Reed Mahoney (shoulder) failed a fitness test on Thursday morning and coach Brad Arthur confirmed the hooker won't play. Ray Stone will take his place while utility Will Smith has earned a bench spot as a dummy-half back-up.
"[Reed] just lacks a little bit of power passing the ball, so there's no need to play him," Arthur said.
"We had a plan to give Reedy a bit of rest over the last couple of weeks just to make sure he was freshened up at the end of the year."
Reserves Stefano Utoikamanu and Haze Dunster were the two players dropped from the squad an hour before kick-off.
In other changes to the 17 which beat the Warriors, Andrew Davey has come onto the bench in place of Marata Niukore (rib).
Samuel Hughes was the other player to drop out of the squad on Thursday.

Nathan Cleary v Mitch Moses. There's some good halfbacks around but Cleary sits on top of the pile. He has been a model of consistency in 2020 and plays like a man who only has eyes for a premiership.
Top-four showdown marks 100th Battle of the West
Moses has all the skills and can dominate a game but hasn't shaken off his tendency to coast in other games. He will have to be at his absolute best in his clash with Cleary.
Don't be surprised if the score is 16-10 in Friday night's showdown. That's what it was when the Eels handed Penrith their only loss of the season in round five and it was exactly the same score when the Panthers beat Parra last year in round 11. Their other meeting in 2019 finished in a 20-12 victory to the Eels, so there might not be many points scored when they square off on Friday.
