The Club commenced discussions with Morgan recently, following a recent horrid run with injuries to its outside backs stocks.
Melbourne Storm Football Director, Frank Ponissi, said the signing of Morgan was a welcome addition to Storm’s NRL squad.
“Ryan will very much be a welcomed addition to our squad, adding much needed depth to our outside backs.
“We also see Ryan’s signing as an opportunity to bring further experience to our roster,” Ponissi said.
Morgan, 26, is a Parramatta junior and made his debut for the Eels in 2011. He has played 84 NRL games.
Morgan will commence with Melbourne Storm immediately.
