Harlequins scrum-half Danny Care faces a race against time to be fit for England's Six Nations opener after suffering an ankle injury in Saturday's Heineken Cup loss to Clermont.
Care limped off during the second half of the 16-13 defeat and Harlequins boss Conor O'Shea has revealed that he may struggle to recover in time for England's opener against France in Paris in three weeks.
"Danny twisted his ankle and he's got a protective boot on," said O'Shea. "We'll review it on Monday and see where he's at. It's pretty sore at the moment but hopefully he will be alright.
"I hope he'll be okay for a few weeks' time but I doubt he'll be all right for next week."
An outrageous offload from the scrum-half set up Matt Hopper's first-half try and O'Shea praised Care's skill.
"We didn't start particularly well but then a piece of absolute genius from Danny changes the energy our way and we were pretty much on top for the rest of the first half," said the coach.
"Danny's piece of skill was quite exceptional. You can't practice that. People may ask if we overplayed in the second half but it was Danny tapping and going 35 yards from our own line. He gave us a bit of momentum and he's a game changer."
