TEENAGER Tyler Morgan will join James Hook in a World Cup audition on Saturday just four years after having a poster of the Wales star on the wall of his bedroom.

The 19-year-old from Caerleon will win his first cap against Six Nations champions Ireland at a sold-out Millennium Stadium (kick-off 2.30pm), getting the chance to show why so many have tipped him for the top.

Morgan's rise has been rapid since a first introduction into the Dragons squad at the end of the 2013/14 campaign following some superb performances with Newport RFC.

The teenager has just 22 senior appearances to his name but is on a national dual contract and his name will soon be on the board of Wales internationals outside the home changing room at the Millennium Stadium.

He has a chance to force his way into Warren Gatland's World Cup squad just four years after being a GCSE student at Caerleon Comprehensive while the New Zealander was using warm-ups with England and Argentina to make his final decisions.

"I would have been watching on TV with my dad and it seems a long time ago now," said Morgan.

"I remember watching the likes of James Hook playing and I had a poster of him on my wall showing how to kick. Now I am playing with him on the weekend – it's ridiculous.

"The first few weeks were a bit surreal in the Six Nations, I sat there in awe of who I was with but now I am comfortable and have bedded in."

Morgan is one of six players who are poised to make their Wales debuts in Cardiff and a strong showing would inch him closer to being named in Gatland's final 31 for the World Cup.

The Dragons tyro, who is on a national dual contract, is in pole position to profit from Jonathan Davies' injury misfortune to act as back-up to the first-choice midfield pair of Jamie Roberts and Scott Williams.

Gatland stressed on Tuesday that the management team would telling Morgan to express himself and not worry about the pressure of a Test debut but that's easier said than done with England 2015 on the horizon.

"Everybody has still got a chance and this game is going to be really important," said the centre.

"Everyone is in the dark about who is going to be in, there are some players who are cemented but there are a lot of spaces still to fill and this game is going to decide who goes there.

"It's a massive opportunity for the new boys playing alongside some experienced players at a sold-out stadium, you couldn't ask for much better."

Morgan may be just 19 but he has already played at the Millennium Stadium two times, making his first Guinness Pro12 start against the Ospreys at Judgement Day in 2014 before showing his talent with a dazzling attacking display against the Scarlets last April.

Those fixtures provided a first experience of a bumper crowd but things will go up another level this weekend with no seats unsold for the Irish encounter.

"At the moment I am just trying to get on with things, do the analysis and training, but I think on Saturday I will be nervous and it will be interesting to see how I react on the day," said Morgan.
