Scarlets and Wales back-row Dafydd Jones has undergone a second operation on the shoulder injury that ruled him out for most of last season.
Jones, who turns 31 this month, is expected to be out for another four months, although he hopes to return by October for the Heineken Cup campaign.
"Obviously it is really frustrating for me that I'm going to be out for a bit longer," said 42-cap Jones.
"But there was no real option for me but to have this second operation."
