Wales prop Adam Jones suffered a calf injury in training

Wales have been hit by the withdrawal of Adam Jones for Saturday's second Test against Australia in Brisbane.

The Ospreys tight-head injured his calf in training and will be replaced by Harlequins prop Ceri Jones.

Worcester prop Chris Horsman is heading to Australia as back-up and should arrive in Brisbane later on Thursday.

Forwards Michael Owen and Mefin Davies return to the Wales side for the Suncorp Stadium clash, with wing Aled Brew set to win his second cap.

Horsman's call-up - he will go straight onto the bench in Brisbane - comes because Dragons rookie Jamie Corsi is also carrying an injury.

Ceri Jones is normally a loose-head but will take over the number three shirt in the injury-enforced absence of namesake Adam.

Owen, normally a number eight, is at lock in place of the injured Brent Cockbain, while Davies takes over from Matthew Rees at hooker.

Brew, who missed the first Test loss with a ligament strain, has been passed fit to start.

That sees captain Gareth Thomas move to full-back to accommodate the Osprey, Lee Byrne dropping out of the 22.

Brew comes in on the left, with Blues flyer Chris Czekaj switching flanks to the right wing.

Centre pairing Jamie Robinson and Sonny Parker have recovered from their respective hip injures to continue on midfield, with Gavin Henson again on the bench.

New Dragons recruit Andy Williams is giving the reserve scrum-half role, Gareth Cooper dropping out of the squad after his lacklustre cameo role at the end of the first Test.

Blues open-side flanker Robin Sowden-Taylor is also on the bench alongside regional team-mate Scott Morgan, a non-playing reserve last weekend who is still waiting for his first cap.

Owen has not played for Wales since the November international against the Pacific Islands, while Davies' last cap was in the 2006 Six Nations defeat to France.

Cockbain has not recovered from the head injury that forced him off in Sydney and Owen continues in the second-row after taking over from the Osprey in the 35th minute at Telstra Stadium.

New Leicester recruit Davies comes in for Scarlets hooker Rees, who has returned home to be with wife Becky for their birth of their first child.

"Mefin will use all his international experience to slot into the front row and pick up where Matthew left off," said Wales coach Gareth Jenkins.

"We are fortunate to be able to call on someone of his international stature.

"Gareth (Thomas) will be able to get more involved in the action from a more central role at full-back and the move also gives us the opportunity to look at Aled Brew, who is a hot prospect for us on the wing.

"Michael Owen deserves his chance to start after impressing from the bench last week when Brent picked up his knock to the head.

"His ability to play in the second row allows us to keep the back-row unit together.

"We have a group of players on the bench who will be able to come on and make an impact if necessary.

"Robin Sowden-Taylor and Andy Williams add to a good mix including Gavin Henson and Ceri Jones, who both impressed when given game-time last week."
