Ospreys wing Tom Grabham has been ruled out for the rest of the season and will miss the Pro12 play-offs.
Grabham, 23, has failed to recover from an abdominal strain sustained during the win over Cardiff Blues in April.
Ospreys' medical team decided, following consultations with specialists, that Grabham should have surgery.
"He has undergone a minimally invasive procedure to repair the damage," Ospreys said in a statement.
"[He] will rehab over the summer with a view to returning to training for pre-season.
Ospreys face Munster away in the play-off semi-final on Saturday with Glasgow or Ulster awaiting the winners in the final on 30 May.
