Sebastien Haller has left Borussia Dortmund's pre-season training camp in Switzerland and has been diagnosed with a testicular tumour.
The 28-year-old, who joined the German outfit earlier this summer, complained of feeling unwell during training on Monday. After a number of examinations, a tumour was discovered. Haller will now spend the next few days in a 'specialised medical facility' where he will undergo further tests.
Reacting to the news, Dortmund sporting director Sebastian Kehl told Borussia Dortmund's official site : "This news today came as a shock to Sebastien Haller and to all of us. The entire BVB family wishes Sebastien a full recovery as soon as possible and that we can hug him again soon. We will do everything in our power to ensure that he receives the best possible treatment."
