AP – Borussia Dortmund striker Sébastien Haller has a testicular tumour and has left his new club’s preseason training camp, Dortmund said on Monday.
Dortmund said the 28-year-old Ivory Coast international complained of feeling unwell at training on Monday and the tumour was found during a medical examination.
Tumours can be benign and do not always lead to a diagnosis of cancer.
“This news today came as a shock to Sebastien Haller and everyone else,” sporting director Sebastian Kehl said in a statement.
“The entire (Dortmund) 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.”
Dortmund signed Haller this month from Ajax as a replacement for Erling Haaland after the Norwegian left for Manchester City.
Ajax said Dortmund paid EUR31 million, with another EUR3.5 million in potential further payments.
Haller scored 34 goals for Ajax last season, including 11 in eight Champions League games, to reignite his career following an underwhelming two-year stay with West Ham in the English Premier League.
