Fin Bartels will undergo a small operation on his knee this coming Monday. The 32-year-old is likely to be out of action for a maximum of four weeks, as Werder’s head coach Florian Kohfeldt announced on Thursday. “Unfortunately his knee has not yet recovered. It’s not a dramatic operation and he won’t be out for a long time, however, it is of course annoying because it’s another setback for him,” Kohfeldt explained.
