Surgery sidelines Tindall
Mike Tindall is set to miss Gloucester's Aviva Premiership title push after undergoing an operation to repair ankle ligament damage.
Tindall, who captained champions England in four of their five RBS 6 Nations games this year, suffered the injury in the first half of the win against Scotland.
The Gloucester centre missed Saturday's 24-8 defeat to Ireland and had surgery on the ankle on Monday.
In-form Gloucester won the LV= Cup on Sunday and are currently third in the Premiership table.
England manager Martin Johnson said: "Tindall was examined under anaesthetic and they decided to operate.
"He had an operation on the medial deltoid ligament in his ankle with an expected return of around 12 weeks."
Tindall is set to miss the remainder of the season and England's non-cap international against the Barbarians at Twickenham at the end of May, but Johnson is confident the lay-off will not affect his chances of competing in the World Cup in September.
"Am I concerned about him? Not a guy of his experience, no," added Johnson. "When you look at the games for some players between now and the World Cup, there aren't a huge amount if their clubs don't make the play-offs.
"We will manage all the players individually. Some guys might play in the Barbarians game at the end of May if they have missed a bit of rugby and are on their way back from injuries.
"Hopefully they will all go through the rest of the season playing well, get a good break and then come in. We will run some camps before June 20, which is the official World Cup camp. If we need to bring people in for fitness and medical reasons in May, June we will do that."
