Former Eel Joseph Paulo, who has played 147 NRL games without a playoff game, is also set to break his playoff duck with the third-placed Cronulla Sharks, leaving five long-term Warriors at the top of the heap.
The unluckiest Warrior is the ever-present Mannering, who has been a consistent performer in a slew of under-performing Warriors squads. Mannering has played 129 games since his last playoff game, and is followed by fellow regulars Shaun Johnson (126 games), Jacob Lillyman (123 games) and Ben Matulino (122 games). Bodene Thompson (123 games) also hasn't been to the playoffs since 2010, having failed to make the eight with the Warriors (2015-2017), Tigers (2013-2014) and the Titans (2011-2012).
Other long streaks which are set to continue until 2018 include Tigers forwards Elijah Taylor (118 games) and Aaron Woods (117 games), while Nate Myles (120 games) and Brad Takairangi (118) are both in line to break their lengthy droughts with the Melbourne Storm and Eels respectively.
As a result, it looks set that the Warriors' players will hold the longest playoff droughts in the NRL, and that barren stretch may continue next season, according to former Kiwis and Warriors coach Brian McClennan.
"They've obviously got a plan in their mind of how they want it to be and they're heading towards that, [but] I think it's going to be another hard year next year really, the way things are going. I think they'll improve, but will it be enough? I'm not sure," McClennan told Radio Sport.
"I don't see it getting dramatically better, I think it takes time. There are little progresses there, but if I'm putting money down next year on whether they'll make the eight, I would say no. I think this re-build is going to take a little bit of time."
That time may be something the veteran Warriors don't have on their side, as they face another year at home during the finals series.
