*United States forward Jozy Altidore will miss Sunday’s Group G World Cup match vs. Portugal due to a strained left hamstring, the U.S. federation confirmed on Thursday.

“He will not be available for Sunday’s game, but we are hopeful he will be available in the tournament,” U.S. Soccer spokesman Michael Kammarman said of the 24-year-old.

The Americans complete the group stage against three-time champion Germany on June 26.

Altidore left the Americans’ World Cup opener against Ghana after straining his left hamstring in the 21st minute of Monday’s 2-1 win against Ghana, leaving his status for the remainder of the World Cup in question.

The forward was running down a ball with Ghana’s John Boye when he lowered his head to attempt to control it, grabbed the back of his left leg and fell to the ground. Wincing in pain, Altidore was taken off on a stretcher.

Aron Johannsson replaced Altidore after the 21st minute against Ghana.
