Werder Bremen have a concern over goalkeeper Karl Hein ahead of their clash with league leaders Borussia Dortmund. The 24-year-old has returned early from the Estonia national team due to muscular complaints and will miss their Nations League match against Iceland on Tuesday. He will undergo further examination in Bremen, casting doubt on his availability for Friday's trip to the table-toppers.
Alongside Hein, outside defender Felix Agu is also a worry. He was substituted with muscular problems during the 7-0 friendly defeat at Twente Enschede and is scheduled for an MRI scan on Monday. Agu has not played a single match this season and has a history of recurring injuries. The international break is therefore not going smoothly for Werder Bremen.
Ole Werner's side face Bundesliga leaders Borussia Dortmund away on Friday evening. Werder themselves sit eighth in the table with seven points from four matches. Their recent form of three wins, one draw and one loss from the last five competitive games offers some encouragement. The outcome of the medical checks for Hein and Agu will significantly shape preparations for the tough away fixture, which is next on the fixtures list.
