U.S. national team defender John Anthony Brooks will miss two to three weeks after injuring his right arm Sunday with Hertha Berlin.
Brooks left the match againt Freiburg in the 20th minute. An MRI revealed Brooks had an hyper-extended elbow, a muscle tear in his forearm, and a small radius fracture, Hertha Berlin announced Monday.
The injury could cause Brooks to miss the United States' final two World Cup qualifying matches in October.
Brooks, 20, has yet to play in an official match with the U.S. and is still eligible to play for Germany if he chooses to do so.
Brooks debuted with the U.S. in a friendly against Bosnia and Herzegovina in August and was an unused substitute in a World Cup qualifier at Costa Rica on Sept. 6.
The U.S. released him back to Hertha Berlin before beating Mexico on Sept. 10.
The Americans, who qualified for the World Cup after the Mexico win, host Jamaica on Oct. 11 in Kansas City, Kan., and travel to Panama on Oct. 15.
