Alun Wyn Jones has pledged his rugby future to the Ospreys and Wales by re-signing his national dual contract.
The 30-year-old lock ended months of speculation over his future following interest from England and France by committing to new terms.
Jones has won 94 caps and captained the 2013 British and Irish Lions in a series-clinching third Test against Australia in Sydney.
He has made 197 appearances for the Ospreys and the news provides a timely boost for Wales, who kick-off their Six Nations campaign against Ireland in Dublin on Sunday, February 7.
"I'm very happy to be in a position to sign an NDC to continue playing in Wales for the Ospreys," said Jones. "I'm grateful to everybody involved for giving me the time to make the correct decision for myself, my family and my career.
"With my future now sorted I can continue to represent the Ospreys, my home region, and put myself in contention for selection for Wales."
Welsh Rugby Union Group chief executive Martyn Phillips, said: "Huge credit must go to the Ospreys for securing Alun Wyn for the next chapter of his career with region.
"I'm convinced that their strong purpose, vision and ambition for the region motivated Alun Wyn to stay rather than pursue other options that he may have had.
"In my mind he is right up there as a leader, on and off the pitch, in the game globally and it's a significant boost to us all in Welsh rugby to see his commitment to the game in this country."
