Former Manly five-eighth Blake Green has signed a three-year deal with the Warriors, a day after being released from his Sea Eagles contract.

Green, 31, helped propel Manly into the top eight in 2017 and is the Warriors' eighth signing for next season, joining Melbourne's Tohu Harris, Cronulla's Gerard Beale, Broncos pair Adam Blair and Matiu Love-Henry, Gold Coast duo Agnatius Paasi and Leivaha Pulu and Warrington's Peta Hiku.

"We're delighted we've been able to sign a player of Blake's calibre," Warriors CEO Cameron George said.

"He wasn't off-contract but became available through circumstances. It couldn't have worked out better for us. He's a terrific player and his experience in winning titles and playing so much finals football will be of huge benefit to us.

"His presence will add both depth and intense competition among the halves, which is exactly what we're after. On top of that his background at a number of clubs in the NRL and Super League makes him an ideal mentor for our young halves."

Green, a Super League premiership-winner with Wigan and former playmaker at the Melbourne Storm, is set to join Shaun Johnson in the halves for the Warriors in 2018 after the exit of Kieran Foran to the Bulldogs.
