The newly-signed striker will most likely stay out of action for several more months.
Borussia Dortmund director Sebastian Kehl has confirmed Sebastian Haller has had a successful operation to remove a tumour.
The Ivorian star moved to Dortmund from Ajax earlier this summer. But he was diagnosed with testicular cancer a few weeks after his arrival at the club.
“The operation went very, very well and he is on the right track,” Kehl told 1&1.
“He was super stable and incredibly positive and also said to the team: ‘Do your job, give everything. Make sure that when I come back we’re still in the running.’ And the boys will do that too.”
It has not been decided when the forward will be able to feature for the Bundesliga team, but Kehl admitted: “He will definitely be out for a few months.”
Dortmund signed Haller as a replacement for Erling Haaland, who left the club to join Manchester City. Kehl confirms the club will look into other options as Haller prepares for a lengthy time on the sidelines.
“We are preparing for different scenarios,” he said. “Edin, [CEO Hans-Joachim Watzke] and I are talking to the scouting department and working on different options and ideas. Nothing concrete at the moment.”
He added: “Nevertheless, Haller is missing the profile. We’re working on different options. But we’ll only do something if it makes sense in the end.”
