Wales prop Gethin Jenkins underwent surgery to repair a ruptured bicep on Tuesday.
The 36-yer-old suffered the injury in the Blues’ recent PRO12 clash with Ulster and faces an estimated three months on the sidelines.
Cardiff Blues head coach Danny Wilson admits it is a blow but he is convinced the Wales record cap holder will do everything within his power to return ahead of schedule.
“Gethin is having surgery today on a ruptured bicep which means he will be out for around three months but knowing him he’ll be back before that,” Wilson told the Cardiff Blues website.
“He is one of the most professional men in terms of prehab, rehab and looking after his body. Whatever he is asked to do to get that right I know he will do it and I imagine he’ll be back before three months.
“It’s a big blow for us and it’s a big blow for Wales. He keeps proving to people that age is just a number.
“His performances for Cardiff Blues and Wales have been of a real high standard. That’s how he got the shirt back with Wales and that’s how he’s kept hold of it.”
