Leeds United midfielder Tyler Adams is set for an extended spell away from the team after undergoing a hamstring operation.
Adams missed the Premier League match at Wolves on March 18 and didn't play for the United States in its games against El Salvador (a 1-0 win) on Monday and Grenada (a 7-1 victory) on Friday.

The 24-year-old has undergone what was described by sources as a "noninvasive" procedure after consulting a specialist. Leeds is waiting to discover how much of the remainder of the season he is likely to miss, and hasn't commented officially on it.
Adams has been a key player for Leeds since joining from RB Leipzig in the summer, and his absence would be a major blow to the team's chances of staying in the Premier League.
The club is in 14th place, two points above the relegation zone, with 11 league games remaining.
