St Helens centre Mark Percival has signed a new five year contract to remain at the club until 2024.
Percival came through the academy at Saints and made his debut in 2013. Since then, he has scored 88 tries and 225 goals in 158 games.
He has also won two League Leaders Shields and two Super League titles with the Saints.
The England international told the club website: “I am over the moon. I have loved being at this club since I joined at the age of 14. Leaving has never really come into my mind and to be offered a five year deal, I am buzzing.
“I have known Mike (Rush) and Eamonn (McManus) for a long time now and for them to put their faith in me to be at this club for so long is something I am humbled by and I want to repay them with my performances.”
Head Coach Kristian Woolf added: “I’m delighted Mark has signed a new deal with us. He’s as tough as they come and although only in his mid-twenties is a player with a vast amount of experience.
“Having won two Grand Finals he clearly knows how to win and that is hugely beneficial to our group and the younger players. We will miss Percy over the coming weeks given his injury, but when he is back fit I have no doubt he will continue to be an important player for us over the coming years.”
