Clint Dempsey will miss both of the United States' upcoming friendlies with a hamstring injury, U.S. Soccer announced on Tuesday.

The Seattle Sounders forward injured his right hamstring in training on Monday and will be sidelined for 2-3 weeks.

The injury will prevent him from playing against Denmark on Wednesday (3 p.m. ET, ESPN/WatchESPN) or March 31 against Switzerland.

Dempsey left the U.S. camp in Zurich and returned to Seattle on Tuesday.

The U.S. will not add a player to replace Dempsey on the squad, which also features forwards Jozy Altidore, Aron Johannsson and Rubio Rubin.
