Ospreys and Wales loosehead prop Paul James faces a spell on the sidelines after undergoing eye surgery, his region confirmed on Friday.
James, who captained the team against the Scarlets last Saturday, was referred to an eye specialist after he suffered a problem at the weekend.
"As part of Paul's routine post-match medical check on Saturday, the doctor identified and eye problem and referred him to a specialist for consultation. His advice was that surgery was required to prevent the issue worsening," said Ospreys Medical Performance Manager, Chris Towers.
"Paul had an operation on Thursday. We'll continue to consult with the specialist, and are still awaiting further details of his after care."
