WALES may be “battered and bruised” after three big physical challenges this autumn but being ravaged by injuries will benefit them in the long run, says forwards coach Jonathan Humphreys.

Alun Wyn Jones, Ken Owens, George North, Leigh Halfpenny, Taulupe Faletau, Justin Tipuric, Josh Navidi, Ross Moriarty and Dan Lydiate are all out injured as Wales gear up for Australia on Saturday.

Forwards Will Rowlands and WillGriff John are “unlikely” to tackle the Wallabies, while Josh Adams (calf), Tomas Francis (concussion) and Aaron Wainwright (shoulder) face late fitness tests.

The weekend’s clash at Cardiff’s Principality Stadium is the last of the “most challenging” autumn series Wales have ever had, according to former hooker Humphreys.

But despite defeats to New Zealand and South Africa, Humphreys believes the testing circumstances has created opportunities to improve the depth of the squad.

“We are extremely lucky to be playing the top three sides in the world and then Fiji who are always a massive physical challenge,” he said.

“It’s been excellent for us in terms of finding out about people who can add to our depth.

“Those injuries have forced players to play who probably wouldn’t have played much.

"So rather than look at the negatives of missing all these people, the bigger picture is telling us we've got a team that can fight toe-to-toe with all those injuries and that's a huge positive for us."

“We’ve got a team here that is battered and bruised on the back of the most challenging autumn we’ve ever had.

“We’re probably as deep as we can go in nearly all positions.

“The tanks are low but come the weekend they are going to be right and ready for the fight against one of the best teams in the world coached by one of the best coaches in the world.”

Commenting further on the autumn series, he said: “We were always going to start slowly. We were up against arguably the best side in the world (New Zealand).

“To be in that game until 68 minutes and 12 points down, and then to go against South Africa for 74 minutes and go toe-to-toe with them missing a huge amount of people.

“We’ve got five people in the pack who have done 80 minutes back-to-back and then gone up against Fiji. It wasn’t perfect against Fiji but we found a way to win.”

He added: “It’s been an incredibly positive campaign.”
