Sean Scannell has extended his Huddersfield Town contract.
The wideman’s new deal runs until 2019, with a further year’s option in the Championship club’s favour.
Former Crystal Palace player Scannell, 25, was previously contracted to 2017.
The Londoner joined Town in 2012 for a reported £800,000 and has made 91 starts and 55 substitute appearances, scoring nine goals.
Watch David Wagner look ahead to Derby trip
Scannell is back in training after a knee injury sustained in January.
He is unlikely to feature at Derby County but could be in contention for a return to the squad at home to Reading on Tuesday.
Town head coach David Wagner said: “I am very happy that Scanz has signed a new contract with us.
“He is a great Championship player with the potential to develop further and a great character.
“He is one of the players who has taken our idea and identity onto the pitch every time he has played.
“As I have already said, securing our talented players for the future is just as important as looking to bring new players in.
“This is the latest step in doing this, following on from Joe Lolley, Harry Bunn and Joe Murphy.”
