Harlequins director of rugby Conor O'Shea has announced that prop Joe Marler has been ruled out for the rest of the season due to an injury.
The England international was a late withdrawal from the Quins line-up that defeated Sale Sharks on Saturday as he is suffering with a shoulder injury.
According to O'Shea he could require surgery but he stressed the loosehead prop would be fit to play for his country during the upcoming World Cup.
"It's not a worry for the World Cup," he told Press Association Sport.
"He came back from the Six Nations with a shoulder injury. We thought because he had this problem before that you could strengthen it, but we made the decision yesterday.
"Will he be fit for the rest of the season? No. But will he be fine for the (England) training camps? Yes.
"It's a hangover from the Six Nations and needs to be looked at. He will probably need an operation but it's only a minor one, it's not going to be something that's going to have any impact on him. We thought he could strengthen but it's not something you can mess around with."
