Calf injury will keep American Agoos out for remainder of the W

Jeff Agoos' difficult World Cup is over, ended by a calf injury.

The 34-year-old defender, injured in Friday night's 3-1 loss to Poland, will be sidelined for 4-to-6 weeks because of a strain in part of his calf muscle, the U.S. Soccer Federation said Saturday.

Agoos began the tournament with 130 international appearances, the most among players who had never appeared in the World Cup.

He scored an own goal in the opening 3-2 win over Portugal when he tried to clear the ball, but put it past goalkeeper Brad Friedel. Then, against South Korea, he was called for a foul in the penalty area - Friedel saved the kick - and was beaten to a header on the Red Devils' goal in a 1-1 tie.

In Friday's loss, he missed a header trying to clear a corner kick, leading to Poland's goal in the third minute, and was beaten to a pass that led to a score that put Poland ahead 2-0 in the fifth minute.

"We are very disappointed for Jeff," U.S. coach Bruce Arena said. "He has made an outstanding contribution to this team."
