United States international Josh Sargent will be out until January with a hamstring injury, his club, Werder Bremen, has announced.
Sargent, 19, picked up the injury in the U.S.'s 4-0 victory over Cuba in CONCACAF Nations League play last month, according to a team release.
After playing the full 90 minutes against Cuba, he came on as a substitute in Werder Bremen's match against Wolfsburg on Dec. 1, but complained about the pain in the subsequent training session.
"Since this is a small, deep-set muscle, the problems only occur at certain, very specific loads, which is why he was able to play and train for so long with problems. We will now give Josh's injury time to properly heal, then he will get back to training in January," said Bremen manager Florian Kohfeldt.
Bremen have four games remaining before the Bundesliga takes its winter break. They we will restart the campaign on Jan. 18 at Fortuna.
Sargent has made 13 appearances this season, scoring two goals thus far.
