Dortmund defender Neven Subotic has left the club for Koln on loan till the end of the 2016-17 season.
The 28-year-old defender was close to joining Middlesbrough in the close injury, but a rib injury he sustained ended that move.
Subotic is yet to make an appearance for the BVB this season due to injuries and his chances of first team football are relatively slim.
Consequently the centre-back has been allowed to leave Dortmund on a temporary basis.
“Bearing in mind what Neven has done for BVB, we decided to meet the player’s request to be allowed to join Koln on loan until the end of the season in order to gain match rhythm at the highest level,” sporting director Michael Zorc said.
Subotic joined Dortmund from Mainz in 2008 and has since made over 200 appearances in all competitions for the club, winning the Bundesliga title in 2011 and 2012.
“The way Neven identifies himself with Dortmund is quite rare in modern football,” CEO Hans-Joachim Watzke added.
“Even though Neven will leave us on a temporary basis, we will keep him as a friend forever. Dortmund are and will always be his home. He is always welcome here.”
