WALES international Tyler Morgan could be used as an impact sub by Newport Gwent Dragons in their Guinness Pro12 opener at Ulster on Friday evening, writes Chris Kirwan.

The 20-year-old centre/wing did not in pre-season after touring New Zealand with the national team, when his sole appearance was in the midweek loss to the Chiefs in Waikato.

Adam Warren, Jack Dixon and Sam Beard have lined up in midfield in the fixtures against Cardiff Blues and Exeter while Pat Howard and Adam Hughes have been used on the flanks along with Warren.

But national dual contracted Morgan adds an extra dimension and the Dragons are tempted to use the game-breaking abilities off the bench in Belfast on Friday (kick-off 7.35pm).

"We might involve Tyler against Ulster," said head coach Kingsley Jones. "We had a chat with (Wales coaches) Warren Gatland and Rob Howley and we all feel that he needs to play.

"Tyler is chomping at the bit and I might select him on the bench, although that might be a bit harsh on one or two players so I have to be careful.

"Hallam Amos will be a bit later because he played three Tests and we will see how that goes, but what I want to create competition and the boys that have played in pre-season have done themselves no harm.

"I have to be sensible and can't just put people straight back in the team; when players have played well I have to reward them."

Influential South Africans Rynard Landman and Brok Harris are likely to come into the tight five after being left out of the Exeter game with niggles while captain Lewis Evans, who was unavailable last Friday, is set to come into the back row.

"My only concern is that they only had 50 minutes against the Blues so it might be a challenge for them over there, so if they start my replacements are made for me," said Jones.

Back row/lock Nick Crosswell will be monitored after suffering a head injury against the Chiefs.

Wings Ashton Hewitt and Tom Prydie are still on schedule following shoulder and knee injuries respectively while fly-half Dorian Jones is recovering from a pubis symphysis problem.

The management should learn shortly whether hooker Elliot Dee needs surgery on the injury to his right ankle that he suffered in the first pre-season game against the Blues.
