Worcester Warriors will be without hooker Matt Moulds for around two months following surgery to repair a long-term foot injury.
The 29-year-old New Zealander has played 12 games for Warriors since his move from Super Rugby side Auckland Blues in the summer of 2019.
Moulds has had a screw inserted during the procedure to "stabilise and strengthen" the foot.
The front-rower is expected to miss August's planned Premiership restart.
Warriors were 10th in the table when the season was suspended in March because of the Covid-19 pandemic.
Meanwhile, Worcester hope prop Conor Carey can return to action in September.
The 29-year-old is continuing his rehabilitation from an Achilles injury he sustained in January's 65-5 defeat against Saracens.
