Wales interim head coach Matt Sherratt has acknowledged the “major weapon” threat posed by Scotland’s back three ahead of Saturday’s Guinness Six Nations clash at Murrayfield.

Wales are chasing a seventh win from their last nine Six Nations trips to Edinburgh, but it is two years since they last tasted victory in the competition.
