Leicester and England flanker Tom Croft has been ruled out for the rest of the season after sustaining knee ligament damage.
Croft returned last season from a broken neck to be part of the British and Irish Lions tour to Australia, winning two Test caps.
However after being tackled in Leicester's 32-15 win over Worcester last Sunday, Leicester boss Richard Cockerill revealed that the flanker would miss the rest of the campaign after surgery on his ACL.
"Tom had a bang on the knee at the weekend. We felt it was relatively innocuous but after further investigation the ACL (anterior cruciate) ligament was ruptured and he has had surgery to reconstruct it and that's his season finished," Cockerill told the Daily Mail.
"It's horrendous bad luck for Tom because it is only last year that he came back from a very bad neck injury and did so well for England but the Lions as well.
"But these things happen. Tom will make a full recovery but it's his season over. It's a blow but we have just got to get on with things."
The news on Croft will also come as a major blow for England and Stuart Lancaster, with the 27-year-old now set to miss the November Internationals and Six Nations.
