Injury-prone utility Chase Stanley will leave Melbourne at the end of this NRL season and rejoin St George Illawarra on a two-year deal.

The 21-year old made his first grade debut for the Dragons in 2007, and played 41 games for the club, before he linked with the Storm in 2010.

However, things haven't gone as planned for Stanley in Melbourne.

Last year he was restricted to just seven matches, while this season is already over for him after he suffered a season-ending knee injury in the first round.

It's a homecoming for the centre/backrower, who was attracted back to the Dragons by the chance to reunite with younger brother Kyle, who also recently re-signed with the club for three seasons.

"There is a really great culture at the Dragons and that family feel is something I have missed," said Chase.

"Playing alongside Kyle was a big factor in coming to the club and the opportunity to play alongside him would be special and one I am looking forward to.

"I am very grateful to the Dragons and look forward to the opportunity to repay their faith in me."

Younger brother Jamie Stanley, 17, who plays in the St George SG Ball Cup team, has also agreed to terms on a two-year contract.

Dragons chief executive Peter Doust says he's delighted with the signing of the three Stanley brothers.

"The Stanley family are certainly very talented and we are delighted that the boys have chosen to sign with our club," said Doust.

"Playing together is important to them and it is great that as local juniors they will have this opportunity at the NRL level with our club.

"Chase made his debut with our club and left for Melbourne where he has continued to develop.

"He will be a valuable part of our squad when he returns next season."
