At least three and as many as six triple-centurions will depart the NRL at the end of season 2019 with their combined departing experience to exceed 3000 games.
Heading the list is multiple premiership-winner Cooper Cronk, who sits second on the all-time games list with 369 – which could be as many as 373 by the first Sunday in October.
With two Dally M medals, one Golden Boot, one Clive Churchill Medal, five Dally M Halfback of the Year nods, 38 Tests, 22 Origins and eight grand final appearances for three premierships, Cronk will take an irreplaceable wealth of knowledge with him when he hangs up the boots.
Fellow 300-gamers Paul Gallen and Robbie Farah have also confirmed their retirements. Each played a key role in NSW's drought-breaking 2014 Origin series win and each was a part of their respective club's first premiership – Farah in 2005 with Wests Tigers and Gallen for the 2016 Sharks.
Gallen will finish on 347 if the Sharks lose on Sunday while Farah is on 302 as he tries to make an early comeback from a broken leg for the Tigers against Cronulla to also make one last finals fling.
Former international Matt Scott (268 games for the Cowboys) has played his last NRL game and Manly veteran Trent Hodkinson (174 for Manly, Canterbury, Newcastle and Cronulla) has also announced he is hanging up the boots.
Scott was an integral part of Queensland's decade of Origin dominance and spent a huge chunk of his career being widely regarded as the best prop in the world. He played 22 Tests for 20 wins and 22 Origins for 13 wins, and was a key part of the Cowboys' 2015 premiership win.
His long-time Cowboys forward comrade, Scott Bolton (246 games), is joining him in the retirement lounge.
Souths veteran John Sutton (333, all for the Rabbitohs) will be looking to qualify for the second grand final of his career while another triple centurion, Benji Marshall (307 for Wests Tigers, Dragons and Broncos), is still unsigned for next year but looks certain to go round again.
The other current members of the 300 club – Cameron Smith, Darius Boyd and Adam Blair (306) – are signed for 2020.
Former Panthers, Sharks, Eels, Roosters and now Titans fullback Michael Gordon will officially pull up stumps after round 25.
Gordon will make his 261st and final NRL start in Gold Coast's clash with St George Illawarra on Saturday night. Gordon also played one Origin for NSW.
Saturday's match at Cbus Super Stadium will also be the last for Jeremy Latimore, who is calling time with St George Illawarra this year after an 11-season career with the Eels, Warriors, Dragons, Panthers and Sharks before returning to the Red V last year. He has tallied 182 games in first grade.
Injury has forced veteran prop Tim Grant into premature retirement - the former Blues prop played 196 games for Penrith, Souths and Wests Tigers.
A series of injuries also forced late-blooming Knights cult hero Nathan Ross into retirement with 60 games, all of which came in a tough period for the Hunter club.
There is also a wealth of experience leaving the NRL for the Super League.
Veteran Storm, Warriors, Roosters, Sharks, Panthers, Blues and Kangaroos playmaker James Maloney has called time on his NRL days, with one final contract at Catalans awaiting the 33-year-old.
Maloney's legacy, aside from being one of the NRL's true characters, will be as a winner – he made every team he joined better, taking the Warriors to a rare grand final appearance in 2011 and winning premierships with the Roosters and Sharks. He also played a key role in the 2018 and 2019 Origin series wins.
Often overlooked is Maloney's endurance – he earned four caps at Melbourne in 2009 as a fill-in but from the time he moved into a starting role from 2010 to now, no other player has played more NRL games.
Of his 247 total games, 243 have come in those 10 seasons, putting him five clear of Cameron Smith (234 in the same period), Adam Blair (230), Alex Glenn (229), James Tamou and Jarrod Croker (both 228).
The others to have confirmed their departure to Super League are Gareth Widdop (194 games for the Storm and Dragons, one premiership), George Burgess (147 for Souths including one premiership), Sosaia Feki (146, all for the Sharks including one premiership), Manu Ma'u (112, all at the Eels) and Mahe Fonua (71 for the Storm and Tigers). Eels forward Tepai Moeroa (109 games) is heading to rugby.
There are a stack of other players late in their career yet to make a call on their 2020 future, including 200-gamers Issac Luke, Ben Matulino, Chris Lawrence and Tim Mannah (233 games), and veteran forwards Shaun Fensom, Sam Tagataese and David Gower.
Between them the confirmed retirees and departures to Super League or rugby will take more than 3000 games of experience with them.
There are another 3000-plus caps shared between late-career players yet to make a call on their 2020 future; some of those will definitely play on but there will likely be enough retire to push the 2019 retirees' class beyond 4000 games of experience, rivalling last year's record tally.
