St Helens prop Matty Lees has signed a new three-year contract with the club.
The 20-year-old made 19 appearances last season as Saints finished top of the Super League table.
“I still feel I have a lot of learning to do but I know that St Helens is the best environment to do that in,” he told the club website.
“We have a great coaching team and players here and they will help me develop further. I’m really looking forward to kicking on in 2019.”
