Wambach ranks third on the United States' all-time scoring list with 118 goals, but has chronic tendinitis in her right Achilles. She sat out the practices as a precaution after playing 90 minutes in each of the Americans' first two games, but said Monday she expected to be able to play against Sweden.
The nagging injury kept Wambach out of the Four Nations tournament in January. The Americans lost the opener of the tournament to Sweden, one of three losses in a five-month span after going unbeaten for more than two years. It also was the U.S.'s first loss to Sweden in almost seven years.
The U.S. needs only a draw against Sweden to win Group C and avoid Brazil in the quarterfinals.
