DORTMUND, Germany (AP) Borussia Dortmund striker Sebastien Haller has undergone a second operation for testicular cancer, which has kept him sidelined this season.
''Operation number 2 went well!'' Haller wrote on Twitter, adding his thanks to his medical team and that he ''can't wait'' to take the next step.
The 28-year-old Haller joined Dortmund from Ajax for 31 million euros ($32 million) in July but had to leave a preseason training camp 12 days later for treatment and an operation after the malignant tumor was found.
He was signed as a replacement for Erling Haaland after the Norwegian joined Manchester City.
Haller had been receiving chemotherapy treatment and told UEFA.com in October that he was hoping to avoid a second operation: ''If I'm lucky enough not to need surgery, things can go very quickly.''
Haller thought he had only a hernia when he asked Dortmund for a scan after first feeling stomach pain while on international duty with Ivory Coast.
The French-born Haller led the Dutch league last season with 21 goals and scored 11 more during Ajax's run to the round of 16 in the Champions League.
