Former Wales flanker Emyr Lewis has said Gavin Henson will have plenty to prove if he rejoins the Ospreys.
BBC Sport Wales understands Henson has held talks with the Ospreys over a possible return to the Liberty Stadium.
"He's got to start from scratch, he's got a point to prove not only to himself and supporters but to his fellow players," Lewis told BBC Wales.
"They're going to give him some serious grief if he starts playing about again and putting 100% into the game."
The injury is likely to keep him out until mid-November and the BBC understands a number of teams including the Ospreys have expressed an interest in signing the British Lion.
Henson is without a club after he left French Super 14 side Toulon at the end of last season.
During his time in the south of France he was embroiled in an off-field incident that led to a one-week ban.
Toulon cited financial pressures and Henson's possible involvement in the World Cup as the reason for not retaining Henson.
He spent a brief spell with Aviva Premiership side Saracens, after his release from the Ospreys in October 2010 after citing personal reasons for wanting to move to a London club.
But in June Henson spoke of his desire to return to the Ospreys in the future and said: "I'd like to think they'd [the Ospreys] take me [back] on."
