Wales fullback Leigh Halfpenny will not be available for this weekend test.
The star fullback has suffered a concussion from a late hit by Aussie Samu Kerevi which was again not picked up by the referee nor citing commissioner.
Wales coach Gatland described the late hit as reckless and should have been carded.
For Wales the player’s welfare comes first, said Howley.
With Halfpenny out they have the option of Liam Williams, Anscombe and Amos.
