[AMERICANS ABROAD] Oguchi Onyewu will again need knee surgery -- this time on his right knee -- after tearing the ligament and meniscus in Sporting's 1-0 victory over Pacos Ferreira Sunday in Portugal. The injury will sideline him for eight weeks.

A tear to the patellar tendon in his left knee during a World Cup 2010 qualifier against Costa Rica sidelined him for seven months and limited him to one game at the 2010 World Cup finals.

He struggled to return to form last season, never playing for AC Milan and seeing limited action for Dutch club FC Twente, with which he finished the 2010-11 campaign.

But he quickly earned a starting job after moving to Sporting and scored four goals for the Lions. He also returned to action with the U.S. national team last fall. His strong game was one of the few highlights of the 1-0 loss to Ecuador in October.

The news of the latest setback comes only eight days before the USA is scheduled to face Italy in Genoa.
