The Blues second-five is rumoured to be returning to the NRL with the Roosters at the end of the Super Rugby season.
Former Roosters player Jimmy Smith made the comments on Australian radio.
"The mail is good," Smith told the Big Sports Weekend radio programme on Sydney radio station 2KY.
"From what I understand, the deal is done. It will be a short stint at the end of the Super Rugby season."
Smith told the Big Sports Weekend on Sunday that the backrower will be back in Bondi before the finals with the Super Rugby final set for August 4.
