Dan Lydiate in danger of missing entire Six Nations after bicep injury

Wales are in danger of losing the services of Dan Lydiate for possibly the entire Six Nations tournament after the flanker sustained a bicep injury.

The 30-year-old sustained the blow while playing for his club Ospreys in the 24th minute of the Pro 14 game against Dragons on Sunday.

"It could be a tendon in the bicep. It's not looking too great," Ospreys defence coach Brad Davis told Ospreys TV.

"You try to look at the best-case scenarios, six-eight weeks, but worst-case scenario, they have got to operate.

"We will know a lot more about that once he has a scan and the medics can plan the way forward."

Wales are already without Sam Warburton while number eight Taulupe Faletau is recovering from a knee injury. Ross Moriarty's participation is also clouded with an injury concern. Meanwhile, Jonathan Davies is another long-term absentee, having been hurt during Wales' November defeat against Australia.

Wales open their Six Nations' campaign against Scotland at Principality Stadium on 3rd February.
