Toovey said Galuvao had done all he could to face the Sydney Roosters on Sunday.
"He's in the mix but it would be highly unlikely. He's had 20 weeks off," said Toovey. "It was a major surgery, but he's trained hard this week to try and prove himself." Toovey will make a final call on his bench tomorrow.
David Gower and youngster James Hasson are in contention for the interchange spot left vacant by Richie Fa'aoso, who suffered a broken neck in last week's preliminary final win over South Sydney. Galuvao has won premierships with Penrith and Manly and also featured in a losing grand final for Parramatta.
Rival coach Trent Robinson said "he wouldn't be surprised" if Galuvao did play.
According to close mate Frank Puletua, nothing can diminish what he believes is one of the "great" NRL careers.
Galuvao has been to five clubs since he debuted as a fullback for the Warriors in 1998.
Since Rabbitohs owner Russell Crowe urged him to hang up the boots in 2007, he's played in two grand finals.
"There's times when the profile of a player can carry them over some of the more difficult times," Puletua said.
"But Joey [has been] able to come back from really the lows of lows you can have in league, where you get thrown outside the unit and basically shown the door."
