St Helens coach Nathan Brown has signed former Castleford Tigers winger Matty Dawson for a second time.
The 22-year-old linked up with Brown at Huddersfield ahead of the 2010 season but made only five appearances for the Giants and has signed a two-year deal with Saints.
“We're pleased to have Matty on board,” Brown said.
“He's quick, talented and keen to learn. He has shown a lot of promise at the Giants and now, like our other younger signings, he needs to get his head down and keep on working.”
Dawson becomes the fifth recruit for St Helens following the signing of Hull KR prop Richard Beaumont, Penrith Panthers duo Mose Masoe and Luke Walsh and Wakefield Trinity Wildcats front rower Kyle Amor.
Saints have also extended the contracts of six of their academy products, including four who made their Super League debuts this year.
Prop or second rower Luke Thompson, 18, stand-off Lewis Charnock, 19, utility forward Greg Richards, 18, and back rower Andre Savelio, 18, have all signed two-year deals while 19-year-old back rowers James Tilley and Connor Dwyer have been given new 12-month contracts.
Dwyer is the son of former St Helens forward Bernard Dwyer.
Brown said: "These are talented young kids who have come through the local system. They all play different positions and have different attributes but are good players who, if they weren't at Saints, would be snapped up by other clubs.
“Lewis, Luke, Greg and James have had a taste of first-team action already and have done well, whilst Andre is training with the first-team squad and Connor will follow soon.”
Huddersfield have also confirmed the departure of second rower Jamie Cording, who made 17 appearances this season but only one in the last seven weeks. The 23-year-old is set to join Featherstone.
Commenting on the departures of Dawson and Cording, Huddersfield managing director Richard Thewlis said: “The players will leave with our very best wishes for the future and thanks for their efforts in the claret and gold.
“Squads continually change and players do move on for many different reasons but I think it's great that all have been retained within professional rugby league and can look to the future with new clubs and new opportunities.”
