Former Scunthorpe United striker Martin Paterson has penned a three-year contract with Burnley.
The 23-year-old still had two years left on his previous Clarets deal left but will now stay at Turf Moor until 2013.
The Northern Ireland international moved to Burnley from Scunthorpe two years ago for £1million since when he has found the net 23 times in 83 appearances for the club.
Clarets boss Brian Laws moved quickly to tie Paterson down to a long-term deal after selling Steven Fletcher to Wolves on Thursday and is also resigned to losing veteran forward Robbie Blake this summer.
The Burnley manager said:"It's absolutely marvellous to see the likes of Martin signing a new, improved contract.
"We feel he is a major player and the fact he is extending his contract now shows he has ambition to help this club back into the Premier League.
"It is a reward for the season he had. Even though he was injured for a good part, Martin certainly made an impact and we want him to be here and nowhere else."
