Borussia Dortmund striker Sebastien Haller has to undergo surgery to remove a testicular tumor.
The 28-year-old Ivorian footballer underwent chemotherapy after being diagnosed with testicular cancer in July.
He wrote on Twitter: “As expected from the start, various possibilities were considered following the chemo.
“I tell you the fight is not over for me. I’m going to have to undergo an operation to get rid of this tumor which keeps me away from the field.’

Haller spent 18 months with West Ham after joining in 2019 for a record £45million from Eintracht Frankfurt.
He moved to Ajax in January last year and signed for Dortmund this summer.
The Ivory Coast international has scored four goals in 15 appearances for Ivory Coast.
Haller had been training with former club Ajax as part of his recovery while rehabilitating in Holland.
After feeling unwell during Dortmund’s pre-season tour of Switzerland, he underwent tests which revealed a malignant tumour.
Haller is yet to make his debut for the Bundesliga giants and has already opened up about his treatment.
Speaking to UEFA last month, he revealed he had spent ‘five days in a row in hospital, where I’m hooked up 24/7’ and couldn’t get out of the bed during the injection of the treatment. He then has a two-week rest period.
‘It’s a phase, and I have to do it four times. Four phases of chemotherapy lasting approximately three weeks each,” he added.
“After that, depending on how my cancer progresses and how it spreads, I might have to have surgery.”
“A lot of people ask me when I’ll be back, but there’s a lot to consider, so it’s hard to give them a clear answer.
