Rees backs Wales youngsters
Former Wales skipper Matthew Rees is confident one of a trio of young props will make an impression this autumn.
Wales are preparing for matches against Argentina, Samoa, New Zealand and Australia without Adam Jones, as he recovers from a knee injury.
Aaron Jarvis, Scott Andrews and Samson Lee are all hoping to be given an opportunity against the Pumas on 10 November, although Wales coach Rob Howley has the option of switching Gethin Jenkins or Paul James across the scrum.
Rees said: "We have props who can play both sides of the scrum, with Paul James and Gethin Jenkins both able to move over, and it will be up to the coaches when it comes to selection.
"But I can certainly see one of these youngsters coming through and getting to the next level over the next three or four weeks.
"Adam is a loss, but we have got three pretty good players there waiting in the wings at the moment, and the challenge for them now is to kick on and impress the coaches and take their chance when it comes.
"The only thing they may lack is experience at international level, but there is no better place for them to get that than in this November series when you look at the fixture list."
