Burnley defender David Edgar has signed a new contract which will keep him at Turf Moor until June 2014.
The 24-year-old's current contract had been due to expire at the end of next season.
"I think it's a reward for his performances and also his attitude and how he has conducted himself," manager Eddie Howe told the club's website.
"He has shown a real willingness to improve on the training pitch, which is so important to us."
Howe added: "I think he will only continue to get better and I think potentially he could be a real asset to this football club."
The Canadian international joined Burnley from Newcastle in July 2009 for £300,000.
He was restricted to just 14 appearances in his first two seasons and ended the 2009-10 campaign on loan at Swansea City.
Edgar has started all but two of Burnley's Championship games this season and Howe said: "He has got better and better.
"He is a young footballing centre-half who previous to this season had not had many games or opportunities.
"We've continually picked him, which I think speaks volumes for his performances of late, especially where he has formed a good partnership with [team-mates] Ben [Mee] and Michael [Duff]."
Edgar's new contract follows the permanent signing of full-back Kieran Trippier from Manchester City, with on-loan City defender Mee expected to follow suit shortly.
