London - Ospreys and Wales flyhalf Dan Biggar has committed his future to his region and to Wales after signing a national dual contract on Friday.
Biggar's new deal will see him remain with his home-town region with an option through until the 2019 Rugby World Cup in Japan.
The 26-year-old, who signed his initial national dual contract back in March 2015, has put pen to paper on a new long-term deal to become the first of the 17 contracted players to re-sign.
"It's taken a little while to get to the point where everyone is happy with the deal, but I'm glad to have the next couple of years sorted and I can continue to play for Wales and, week in, week out, for the Ospreys," Biggar said.
"Hopefully others will follow suit and we can continue to grow a strong player base in Wales."
Welsh Rugby Union group chief executive Martyn Phillips added: "We are delighted Dan has committed his future to the Ospreys and will be remaining in Wales.
"It is another landmark moment for national dual contracts in Wales as Dan becomes the first player to re-sign a deal and it is evidence of our close working relationship with the region to ensure our top players remain in Wales."
Last month centre Jonathan Davies returned to Wales and the Scarlets on a national dual contract to join four Ospreys, Scott Baldwin, James King, Dan Baker and Rory Thornton, who recently signed deals.
The national dual contract structure was agreed by the WRU and the four regions under the terms of their joint Rugby Services Agreement in order to keep the best playing talent in Wales playing for one of the four professional Welsh teams.
