It looks as though you can add Zack Ryder to the list of free agents from ECW that have signed with the RAW brand. While his profile page has not yet been added to the RAW Superstar page on WWE.com, Ryder did work a match during the Superstars taping this week as a RAW Superstar.
Also new to the RAW roster are former ECW stars Christian, Yoshi Tatsu and William Regal.
