The Warriors have signed young Australian prop Jeremy Latimore from Parramatta.
The 22-year-old broke into first-grade against South Sydney in round 11 this season, the last of his seven interchange appearances for the Eels coming against the Warriors in August.
He joins a propping contingent that includes Steve Price, Sam Rapira, Russell Packer, Jesse Royal and Jacob Lillyman, along with fellow youngsters Mataupu Poching and James Gavet from the Junior Warriors.
The Warriors have also confirmed halfback Shaun Johnson has extended his contract to 2012 with an option for 2013.
Johnson is one of five players from the club's 2009 NYC squad who have had their contracts upgraded to full NRL status for next season. The others are Elijah Taylor, Alehana Mara, Sione Lousi and Gavet.
