David Wright, the top hitter for Team USA in the World Baseball Classic, missed Thursday night's game due to soreness in the back of his ribcage.
Without the New York Mets third baseman, the USA lost 3-1 to the Dominican Republic in Miami. The Dominican team clinched a spot in the WBC semifinals, while the USA will play Puerto Rico on Friday in Miami for the last semifinal berth.
Wright is scheduled to be examined by the Mets' medical staff Friday at the team's spring training site in Port St. Lucie, Fla.
Through four WBC games, Wright is batting .438 (7-for-16) with two doubles, a grand slam and 10 RBI.
He said the back problem began before the WBC, but he's played through the discomfort.
"I owe it to the Mets to listen to them and be ready for Opening Day," Wright told reporters. "That is extremely important to me. That's something that obviously I don't want to jeopardize."
Arizona's Willie Bloomquist replaced Wright at third base Thursday, and he went 0-for-2.
Team USA won't be able to replace Wright on the roster for the Puerto Rico game, but it could make a roster move prior to the semifinals, according to MLB Network.
Japan and the Netherlands earlier clinched spots in the semifinals, which will be played Sunday and Monday in San Francisco. The championship game will be played Tuesday in San Francisco.
