U.S. international forward Aron Johannsson will be out for "the coming weeks" after undergoing hip surgery on Wednesday. 

The Werder Bremen man has not played since Sept. 22 after initially suffering a groin strain at U.S. training camp earlier in September. The problem was later diagnosed as a nerve issue in his right hip, and he will now be sidelined several more weeks.

“We have exhausted all non-surgical treatment options and, unfortunately, could not sustain freedom from pain,” said Werder Bremen team doctor Dr. Philip Heitman.

The 24-year-old joined the German club from AZ Alkmaar this summer and has scored two goals in six Bundesliga appearances.

Johannsson missed out on the CONCACAF Cup defeat to Mexico due to the injury, and now appears likely to miss the USA's first two World Cup qualifiers against St. Vincent & The Grenadines on Nov. 13 and against Trinidad and Tobago on Nov. 17.
