Wales have called Ospreys forwards Alun Wyn Jones and Richard Hibbard into their RBS 6 Nations 2012 training squad preparing to take on England at Twickenham on Saturday.
The 59-times capped lock Jones made his second appearance for his region since returning from a toe injury on Friday night and he joins the squad as a direct replacement for Blues second row Bradley Davies, who is currently serving a suspension.
Hibbard, who has featured for his country on 15 occasions, has been called up as cover due to the well documented injury concerns over fellow Ospreys hooker Huw Bennett and Scarlet Matthew Rees (both are recovering from calf strains) and will boost training numbers at the WRU National Centre of Excellence, alongside Jones, to 38 from Monday.
