Young forward James King has signed a new three-year deal with the Ospreys.
The 22-year-old has been part of the squad since 2008 and in his four years with the region has made 48 appearances.
King told the club's official website: "I'm very happy to stay here. I'm still developing as a player and this is the place for me to do that.
"The Ospreys have a great record for providing players to Wales, especially forwards and I want to be playing week-in, week-out for the Ospreys."
Andy Lloyd, rugby operations manager with the Ospreys, added: "James signing a new contract is a huge boost for us.
"He's an outstanding athlete who can play anywhere in the second row and anywhere in the back row.
"I've got no doubt that it's only a matter of time until James goes on to play international rugby so everyone at the Ospreys should be delighted that we've secured him for another three years."
