The German side have once again put their faith in the 28-year-old, who has had a rough time with injury problems since returning to the club
Former Real Madrid and Liverpool midfielder Nuri Sahin has extended his contract at Borussia Dortmund until 2019.
The Turkey international, 28, left Signal Iduna Park for Real Madrid in 2011 for €10 million but failed to break into the Spanish giants' first team.
Following an unimpressive half-season at Anfield in 2012-13 he returned to Dortmund on loan before making his move permanent in 2014.
Since returning to the Bundesliga side, he has been beset by a variety of injury problems that have limited his game time, but that has not stopped BVB from offering him a new deal.
