Midfielder Adam King has put pen to paper on a new three-year contract with Swansea after impressing with the development squad.
Scotland Under-21 international King, who joined the Swans from Hearts in January 2014, had been on a deal set to expire at the end of next season.
The 20-year-old made his sole senior appearance for Swansea to date as a substitute in an FA Cup tie at Tranmere in January 2015 and he spent the first half of last term on loan with Crewe.
King is hopeful of spending more time with the first-team squad this season, although it appears more likely he will spend more time out on loan.
“I am delighted the club have shown faith in me again by offering me another deal,” King said.
“It’s a big thing for me. To kick on again in the next few years is going to be difficult, but I believe I can do it.
“Last season was a good one for me. I was out on loan and then after coming back I had a bit of experience training with the first team and getting to work with the new manager.
“Hopefully I can spend some more time with the first team next season and I’ll see where that takes me.”
