Tyler Adams, who missed the USA's two Concacaf Nations League matches with a hamstring injury, underwent "non-invasive" surgery on Tuesday to repair the injury.
Adams was injured in training ahead of Leeds United's Premier League win at Wolves 10 days ago. The Athletic reported that he faces a long stretch on the sidelines but the exact timetable for his recovery won't be known until next week.
Leeds, which is in a relegation fight, has 11 games left in the Premier League season, which ends May 28 against Tottenham. It faces leader Arsenal on Saturday. The USA's next official match is against Mexico June 15 in the Concacaf Nations League semifinals.
The 24-year-old midfielder has started 24 of 27 Premier League games for Leeds since moving to England from RB Leipzig last summer.
Adams, who captained the USA at the 2022 World Cup, was bothered by adductor issues that forced him to miss eight games toward the end of the 2018-19 Bundesliga season and all but one game in the first half of the 2019-20 season.
The first layoff followed a strong start to his German career after leaving the New York Red Bulls. In the Covid-delayed conclusion to the 2020 UEFA Champions League, Adams scored the winning goal in Leipzig's quarterfinal win over Atletico Madrid.
He missed the 2019 Gold Cup and was used as a reserve at the 2021 Concacaf Nations League finals, which the USA won.
