Wales' Gethin Jenkins expected to miss Six Nations with bicep injury
Wales prop Gethin Jenkins looks set to miss this season's RBS 6 Nations Championship after suffering a ruptured bicep injury.
Jenkins' regional team Cardiff Blues revealed the 36-year-old was undergoing surgery on Tuesday.
Wales' record cap holder with 129 Test match appearances was hurt during the Blues' recent Guinness PRO12 game against Ulster.
The Blues added that he faces an estimated three months on the sidelines.
The news is a major blow for Wales' interim head coach Rob Howley, whose team kick-off their Six Nations campaign against Italy in Rome on February 5.
If Jenkins does take three months to regain full fitness then he is unlikely to play any part in the tournament.
Ospreys prop Nicky Smith understudied Jenkins during the recent autumn Tests, while the Scarlets' Rob Evans would be another option.
Evans started all five games in last season's Six Nations but was unavailable for the autumn internationals due to injury.
Blues head coach Danny Wilson said: " Gethin is having surgery today on a ruptured bicep which means he will be out for around three months, but knowing him he will be back before that.
"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."
