Gavin Henson is likely to miss the start of the season after Ospreys revealed that the centre is likely to be out of action until the end of September.
The Welsh international underwent surgery on his ankle in April after suffering an injury against Saracens in the Heineken Cup.
Originally, Henson had been optimistic about his chances of making it back in time for the start of the new season, but now looks to have admitted defeat.
