Wales' record international try-scorer Shane Williams could be fit for the RBS 6 Nations opener against England in Cardiff on the evening of Friday, February 4.
The Ospreys wing has been sidelined since dislocating his shoulder during Wales' home loss to world champions South Africa last month.
He subsequently underwent surgery and was ruled out for an initial period of 10-12 weeks, suggesting he would struggle to make both the England game and Wales' Murrayfield appointment with Scotland eight days later.
But the Ospreys say there is a chance that former world player of the year Williams, who has scored 51 tries in 75 Tests for his country, might feature ahead of the Six Nations.
Ospreys conclude their Heineken Cup pool campaign against Jonny Wilkinson's Toulon on January 22, which is a possible comeback game for the 33-year-old.
