Goalscorer Sebastian Haller, who is suffering from testicular cancer, has returned to the soccer field.

The Borussia Dortmund striker completed a session on Tuesday at the training ground of his former club Ajax Amsterdam, with whom he won the Dutch championship in 2021 and 2022 before joining BVB. "He asked us if he could come to training because he's in rehab here. Then of course it's wonderful that he can be there for a while," said Ajax coach Alfred Schreuder.

Haller trained on a side pitch, more sessions are to follow. The 28-year-old had undergone surgery for his cancer and is undergoing chemotherapy. According to him, a second operation is also not excluded. He was diagnosed with a malignant testicle tumor in July at the BVB training camp.

Return to BVB training open

Haller was at the Ballon d'Or ceremony a week ago and commented on his state of health there. "Everything is fine. If I'm here today, it's because everything is fine, things are going as well as possible," said Haller. It is unclear when he will return to BVB team training.

Haller recently spoke candidly about his treatment process in an interview published on UEFA's website. "I spend five days straight in the hospital where I'm hooked up 24/7 and can't get out of bed while the treatments are injected into my body. Then I'm off for two weeks. This cycle is a phase and I I have to do this four times in total. Four phases of chemotherapy, each lasting about three weeks," said the Ivorian international, adding: "Depending on how my cancer develops and spreads, I'll have to have an operation."

But he is optimistic and has a schedule in mind. If he doesn't have to be operated on again, "and that would be very lucky, it could even go quite quickly. Three weeks after the last cycle, we look at how the metastases have developed and whether an operation is necessary. If I don't have an operation I think I should be in good shape after these three weeks, also considering my training."
