Kohlschreiber withdrew due to back injury

There are changes in the in the main draw

Philipp Kohlschreiber, seeded N6, withdrew from Garanti Koza Sofia Open. The German, who last year played at the quarterfinals in Bulgaria, was forced to step out because of a back injury.

The Kohlschreiber’s withdraw caused some changes in the main draw. Viktor Troicki will move from his original position on line 6 to line 16 as seed number 9. Line 6 will be filled by a qualifier/lucky loser once the qualifying is complete.

Last year Troicki played in the final in Sofia and was defeated by Roberto Bautista Agut. This year the Serb’s first opponent will be Cem Ilkel (wild card).
