Defender James Tarkowski has signed a new four-and-a-half-year deal with Burnley.
The 25-year-old's new contract ties him to the Lancashire club until June 2022 and replaces the existing deal which expired at the end of next season.
Clarets manager Sean Dyche told the club's official Twitter account: "We felt it appropriate to offer James a new deal on two levels. He's done well in the Premier League and secondly his contract was out of sync. And there's a few more we are talking to."
Tarkowski joined Burnley from Brentford in January 2016 and has become a regular at Turf Moor since Michael Keane departed for Everton in the summer.
He featured in each of the club's first 18 Premier League matches of the season before a retrospective three-match ban was issued last month for his elbow on Brighton forward Glenn Murray.
He also suffered a broken hand in that match against the Seagulls, but returned to action in the New Year's Day defeat to Liverpool.
Tarkowski played the full 90 minutes in place of Kevin Long at Turf Moor, while Dyche confirmed he would be rotating his squad for Saturday's FA Cup third-round tie against Manchester City at the Etihad Stadium.
Midfielder Scott Arfield is expected to miss out after sustaining a hamstring injury on Saturday and joins Stephen Ward, Chris Wood, Robbie Brady and goalkeeper Tom Heaton in the treatment room.
However, Dyche does not share City boss Pep Guardiola's view that a congested fixture schedule was threatening his players' welfare.
"I just get on with it," said Dyche, who stated that most of his players' injuries were sustained before the Christmas period.
"We're as stretched as we've probably ever been, but fortunately our squad, although right at the end of its depth, is a bit more rounded with a bit more depth to it.
"But we just get on with it. I'm not really that fussed. But I must make it clear though that everyone has different challenges.
"Pep and Man City have to win, if not pretty much everything, as much as they can, so a lot of pressure and stress comes with that.
"Ours is to continue improving, so we've got a different kind of challenge. That doesn't mean we don't want to be successful and be as high up the table as we can. Of course we do."
