Gloucester prop Nick Wood has been ruled out for the rest of the season because of a pectoral injury.
The 29-year-old was forced off the field in their 36-3 defeat by Leicester Tigers on 3 March.
He underwent surgery on Tuesday and is now expected to be sidelined for at least three months.
Wood had been an ever-present in the Premiership for the Cherry and Whites this season and also earned a place in the England Saxons squad.
The frontrower has made 201 career appearances for the Kingsholm outfit.
