Prop Tom Spencer has signed a new one-year deal with Leigh.
The 28-year-old returned to the Centurions from London ahead of last season, making 20 appearances for the club.
Leigh boss John Duffy said: “Tom had an injury for quite a while last season as well as some off-field stuff to deal with.
“But he came back for the last game of the season and had a blinder.
“We are looking for him to have a big off-season and kick on and show everyone who he really is.
“I don’t think he did himself justice last season because of those niggling injuries so we’re looking for a big year from Tom and I’m sure he’ll give it to us.”
