DRAGONS speedster Rio Dyer is set to make his Wales debut in the Hamilton leg of the World Rugby Sevens Series.

The 19-year-old Wales Under-20s international from Rogerstone has been called up for the tournament in New Zealand, which starts next Friday, and the following weekend's leg in Sydney, Australia.

Dyer, who made his professional debut at Saracens in the Anglo-Welsh Cup last season, is joined in the squad by fellow Dragons wingers George Gasson and Joe Goodchild while the region's academy coach Matt O'Brien, Newport's fly-half, will be an assistant to boss Richie Pugh.

Will Talbot-Davies, who bagged a brace in the European Challenge Cup win against Timisoara Saracens last week, sits out these legs after featuring in Dubai and Cape Town at the end of last season.

Dyer, the Scarlets' Tom Rogers and Ospreys' Reuben Morgan-Williams are set for debuts at FMG Stadium Waikato while Cardiff Blues back row forward Sion Bennett makes a return.

Pugh said: "Starting with a larger player base this season than we've had in the past has allowed us to prepare well for the forthcoming tournaments.

"Rio and Tom are coming in on the back of injuries, and both have pace and attributes that are well suited to the sevens game. Reuben, who's had quite a lot of regional experience, is rewarded for his form in training.

"Rhe experience and physical presence of Sion Bennett is huge for this group. He last played four years ago, and in the time since he's been with Northampton Saints and Cardiff Blues.

"It's also good to bring back Mike Wilson from Aberavon, who experienced two World Series tournaments last year.

"He's an athlete who still trains as a sprinter, so I'm looking forward to seeing that x-factor he can bring."

Wales have a tough task in New Zealand after being drawn with Fiji, Australia and Argentina.
