The initial prognosis was not promising but Panasonic hope Sonny Bill Williams will play for them again this season.
When he tore his pectoral muscle playing Mitsubishi Dynaboars in late October, it was expected to sideline him until at least the beginning of the NRL season in March.
But Wild Knights head coach Norifumi Nakajima said the club was not ruling out a Williams return.
"We hope he will come back and play for us in the finals series," said Nakajima, through a translator.
"He is a very important player and would be good to have him fit for the play-offs."
