Wales have called Ospreys lock Rhys Davies into Steve Tandy's Six Nations squad. Davies, 27, started in the 73-0 defeat against South Africa in November but was left out of the original 38-man squad for this year's Six Nations tournament. Davies, who has played four internationals, is the eighth Ospreys player named in the squad, when there are doubts about the long-term professional future of the Welsh side. It takes the total number in the squad to 39 with Exeter skipper Dafydd Jenkins, Montpellier lock Adam Beard and Dragons co-captain Ben Carter the other lock options in the squad, and Gloucester forward Freddie Thomas battling back from injury. It is the second call-up this week after Cardiff prop Sam Wainwright replaced his club team-mate Keiron Assiratti, who is set to miss the tournament with a calf injury.
