Benji Marshall concedes Russell Packer "wasn't a great person" before he spent 12 months in jail for assault.
However, Marshall believes his St George Illawarra teammate is sufficiently rehabilitated as to deserve another shot in the NRL.
Packer's return to football has been cleared by the league ahead of the 2016 season but the Immigration Department is yet to say whether he will be deported due to his conviction.
Marshall is one of number of NRL stars who have signed an online petition to keep Packer in Australia and in the NRL.
"It's pretty sad to see someone potentially be deported," he said on Friday.
