Ben Davies has extended his contract with Swansea City until the summer of 2017, the club has confirmed.
The new four-and-a-half-year deal is a one-year extension for the 20-year-old defender, who made his full debut for the senior team in August 2012.
"I'm very happy to have signed the new contract," Davies told the club's official website. "It wasn't a difficult decision and it's always great to sign a new deal and commit my future to the club.
"This is a great place to learn and improve and it's nice to be rewarded for all the effort I've put in.
"I feel as though I'm getting better all the time and this is a good place to play football, especially with the style of play we have at the club."
Davies has played nine times for Wales.
