Sebastien Haller has left Borussia Dortmund’s pre-season training camp in Switzerland after a tumor was discovered in his testicle.
The 28-year-old Ivory Coast striker joined the Bundesliga club from Ajax earlier this month.
Dortmund stated that Haller “complained that he felt unwell after training on Monday” and that medical tests revealed “a testicular tumor.”
Additional tests will be performed “in the coming days.”
“Thank you all for your many messages of support and affection since yesterday’s announcement,” Haller said on Tuesday. My family and I appreciate it. I will now concentrate on my recovery in order to return stronger.”
“This news came as a surprise to Sebastien Haller and everyone else,” Dortmund sporting director Sebastian Kehl said.
“The entire BVB family hopes that Sebastien makes a full recovery as soon as possible and that we can give him a hug again soon.
“We’ll do everything in our power to ensure that he receives the best possible treatment.”
