His new club Borussia Dortmund reports this on Saturday afternoon. The 28-year-old striker therefore has to undergo chemotherapy treatment and is not available for the German top club for a few months. Haller was diagnosed with testicular cancer earlier this month.
“Sebastién is now receiving the best possible treatment and the chances of recovery are very high. We wish him and his family a lot of strength and optimism and our thoughts are with him at this difficult time,” said sports director Sebastian Kehl.
Dortmund asks the media and fans for understanding and says it will not be able to provide medical details about the treatment in the coming months. Haller was taken over by Dortmund from Ajax this summer.
