Wales and Ospreys flanker Dan Lydiate has been ruled out for the rest of the season with a bicep injury.
Lydiate was injured during the Ospreys' 22-9 Guinness PRO14 win at the Dragons on New Year's Eve and will undergo surgery this week.
Ospreys medical performance manager Chris Towers said: "After speaking to consultants and seeking specialist opinion, the decision has been taken in Dan's best interests to undergo surgery.
"That process will take place this week, ruling him out of consideration for the rest of the current season."
Lydiate's unavailability is another blow to Wales boss Warren Gatland, who is already without Lions skipper Sam Warburton and centre Jonathan Davies for the entire Six Nations, while No 8 Taulupe Faletau could miss the start of the campaign with a knee injury.
George North is also sidelined with a knee injury and faces a race to be fit for Wales' opener against Scotland on February 3.
