Borussia Dortmund have confirmed that defender Erik Durm has extended his contract with the club until 2019.
The 22-year-old Germany international's previous deal at the Signal Iduna Park was due to expire in 2017.
"Borussia Dortmund have really pushed my progress to make me the player I am now," Durm told Dortmund's official website. "It's only natural for me to show my appreciation by committing in the long term to a club who have given me so much support.
"I'm absolutely convinced about Dortmund's future and something big is growing here, and I want to be a part of it where possible."
Durm has made a total of 33 appearances for Dortmund since joining the club from Mainz 05 in 2012.
