Injured Shingler leaves Wales squad
Wales flanker Aaron Shingler is to undergo further treatment on an ankle injury.
The Welsh Rugby Union announced that 26-year-old Shingler has been released from the RBS 6 Nations squad back to his regional team the Scarlets.
Shingler picked up the injury in training last week.
He has won seven caps, but he was not part of the match-day 23 when Wales opened their Six Nations campaign with victory over italy two days ago.
