Brighton & Hove Albion defender Lewis Dunk has signed a new four-year contract to keep him at the Championship club until 2018.
The 22-year-old has made over 50 appearances for the club, 11 of which coming last season.
"Lewis has proved he is worthy of a place in our first-team squad and he has a very bright future ahead of him," Albion boss Sami Hyypia said.
Dunk had his first venture into first-team football for Brighton during the 2010-11 season as the club were promoted to the Championship.
Dunk made his debut for the club in May 2010 against MK Dons.
