Bundesliga club Borussia Dortmund will probably have to do without their goalscorer Sébastien Haller, who is suffering from testicular cancer, for a while.

As the 28-year-old Frenchman said in an interview with UEFA, “I’m fine” and his chemotherapy is going well, but he’s not sure when he will return to football.

“I spend five days straight in the hospital, where I’m hooked up 24/7 and can’t get out of bed […]. After that I have a two-week break. I have to do this cycle four times in total. Four phases of chemotherapy , each of which lasts about three weeks,” said Haller, describing the treatment process.

The Ivorian left open when this will be completed. “Depending on how far my cancer has progressed and how it’s spreading, I may need surgery afterwards,” Haller said. “A lot of people ask me when I’ll be back, but there’s a lot to consider, so it’s difficult to give them a straight answer.”

Personally, he has “a schedule in mind,” he emphasized. “If I’m lucky enough not to need an operation, it can happen very quickly. Three weeks after the last phase of treatment, they check what stage the metastases are at and whether an operation is necessary or not. If I don’t need an operation, think I think I’m in good shape at the end of these three weeks.”
