Borussia Dortmund have announced that their striker Sebastien Haller has been diagnosed with a testicular tumour.
The 28-year-old Ivory Coast international joined the Bundesliga side from Ajax earlier this month as a replacement for Erling Haaland, but will now likely miss the start of the season.
The player had complained of feeling unwell, according to a statement on the Borussia Dortmund official website.
