Parramatta fullback Michael Gordon will join the Roosters next season on a one-year deal.
The former Panther and Sharks has been one of the few rocks for the Eels in a tumultuous season this year but had been linked with a move to Bondi for several weeks.
Gordon is expected to act as a mentor to 18-year old rookie Latrell Mitchell.
"With almost 200 NRL matches under his belt, Michael will add experience and depth to our squad," said Roosters CEO, John Lee.
"Michael will also be a terrific mentor as we continue to develop our younger backs, and we're pleased to have secured his services," he added.
