Veteran Castleford prop Andy Lynch has announced he will retire at the end of the season.
On Sunday the 37-year-old will make the 500th appearance of a career that has also seen him represent Bradford - whom he helped win the 2006 World Club Challenge - Hull, England and Great Britain.
He sits second in Super League's all-time appearance list and could break Kevin Sinfield's record of 454 before the end of the campaign.
Lynch, currently Super League's oldest player, told Castleford's official website: "It's an amazing achievement for me to up there with the best, and some great guys - Rob Burrow, Keith Senior and Kevin Sinfield to name a few. I'm really proud to reach this fantastic milestone in my career.
"I discussed it a lot with my wife April and we decided it's the right time for me now to look to the next chapter of my life.
"My three boys are at that age now where I need to be there more at the weekend, they are all playing sports and I've already missed out on a lot with them.
"It's now time to turn the tables and for me to spend my weekend watching by boys play sports."
Lynch started his career at Castleford, advancing through the academy before making his professional debut in 1999, and is hoping to end it with the Tigers winning silverware.
Daryl Powell's side, ahead of Sunday's clash with struggling Warrington, are four points clear at the top of Super League and face Hull in the Challenge Cup quarter-finals next week.
"There is still a long way to go for us this season, we will take each game at a time and work hard to chalk off the wins each week but to bring a trophy back to this club and this town would mean everything to me," Lynch added.
"It's been part of my life since I was 15. I love this club and I will always be a Castleford fan, bringing a trophy home this season would just be a brilliant way to sign off on a career I have truly loved."
Tigers head coach Powell said: "Lynchy has been an awesome player over many years, 500 rugby league games is a lot of games. He's a big man and he does a lot of minutes so it's a fine achievement.
"Andy has been an awesome contributor to this club and to Rugby League in general. He's a great leader and a great driver of standards around the place."
