Lukasz Piszczek has agreed a contract extension with Borussia Dortmund, committing himself to the Bundesliga club until June 2020.
The 32-year-old's new terms bolt a further 12 months on to his previous deal at Signal Iduna Park, which he agreed last April.
Poland international Piszczek joined Dortmund from Hertha Berlin in 2010 and has made 290 appearances in all competitions.
He is one of the remaining members of the side that won back-to-back Bundesliga titles under Jurgen Klopp in 2010-11 and 2011-12.
"We are delighted to - after Marco Reus - tie another player to our club for long term who identifies absolutely with Borussia Dortmund," said chief executive Hans-Joachim Watzke.
