Number eight Aaron Wainwright is a major doubt for the second Test against Australia in Melbourne but Wales say they have not officially ruled him out.

Wainwright, 26, was Wales' leading performer during his 50th international in the 25-16 first Test defeat in Sydney but limped off in the final minute with a leg injury.

"Were waiting for further assessment," said Wales assistant coach Rob Howley.

"He was outstanding in the game. His carries and footwork got us on the front foot on many an occasion.

"So hopefully [he'll be available]. But we're waiting for that assessment to come back from the medical team."

Wainwright has started the last eight Tests in the number eight jersey and arguably been Wales' player of the 2023-24 season.

Wales also have concerns over full-back Liam Williams, prop Gareth Thomas and wing Josh Hathaway, while prop Dillon Lewis and lock Ben Carter are battling to be fit after missing the the game in Sydney.

"Liam will hopefully be available for selection, were waiting on him," said Howley.

"Gareth Thomas had a bit of a dead leg, he was back in training today. Josh Hathaway is being monitored, he had a bump on his arm.

"Dillon and Ben Carter trained this morning with us. Hopefully those players who came off, fingers crossed, will be available for selection."
