Borussia Dortmund head coach Marco Rose confirmed midfielder Giovanni Reyna faces longer-than-expected time on the sidelines after complications from a thigh injury.
The Bundesliga star hasn’t seen the pitch since picking up a hamstring issue while representing the United States against El Salvador on 3 September in a World Cup qualifier.
Officials initially stated Reyna could be out for the standard three to eight weeks while recovering from a pulled hamstring, but Rose now confirmed a tendon and nerves have also been affected.
After several setbacks with the rehab procedure, the Borussia Dortmund manager cannot accurately predict when the midfielder will be available to train with the team again.
"“The injury turned out to be a bit more serious than we expected. It's really not foreseeable for me when he will be back in training with the team, I have to be honest," Rose said. "But we hope that will happen before the end of this year.''
The injury came as a huge blow to the United States men’s national team, who counted on his contributions in the upcoming World Cup qualifier against North American rivals Mexico.
USMNT head coach Gregg Berhalter has since left Reyna off of the American roster for the November window.
Prior to his injury, Reyna had distinguished himself in his club and international career. He scored two goals in the opening three Bundesliga games for Dortmund, while playing a huge role for the United States in their Nations Cup win over Mexico.
Berhalter initially counted on Christian Pulisic and Reyna to match up on the field during the November window, but will have to adjust the starting line up to highlight the Chelsea player alone instead.
The USMNT must now fight harder to reach first place after struggling in their initial World Cup qualifiers. The American side sits in second place with 11 points in six games and a record of 3-2-1.
