ANKARA (AA) - Borussia Dortmund forward Sebastien Haller will be sidelined for several months after undergoing testicular tumor surgery, a team official said Wednesday.
"Sebastien will be out for a few months but once we can be more precise about that we will communicate it," according to Dortmund sporting director Sebastian Kehl.
"The operation went very, very well and he's on the right track," he added.
The French-born Ivorian footballer won back-to-back top-tier Dutch Eredivisie titles in 2021 and 2022 with Ajax.
Haller scored 21 goals to be the Dutch league's top scorer in the 2021-22 season. He also had 11 UEFA Champions League goals last season.
Apart from Ajax, he has also played for French club Auxerre, Dutch team Utrecht, Germany's Eintracht Frankfurt and England's West Ham United.
The 28-year-old moved to Dortmund from Ajax on July 6.
Haller was diagnosed with testicular cancer earlier this month. He had to leave the training camp for intensive medical examinations after complaining of feeling sick.
