The FC Nurnberg right back faces long odds to make the U.S. World Cup squad after suffering an injury setback against Bayern Munich.
The right back suffered the injury in a 2-0 defeat to Bayern Munich. Chandler started the match, but had to be hauled off after just 10 minutes.
The 23-year-old has been in good form for Nurnberg recently, and was a good bet to be called up for the USA's March 5 friendly at Ukraine, after head coach Jurgen Klinsmann said he was keeping an eye on Chandler and would be calling mostly European-based players.
Chandler has not featured for the U.S. since February 2013, when he started in a 2-1 loss at Honduras to open the USA's Hexagonal campaign. The appearance cap-tied him to the U.S. national team.
