"We have to make a decision whether she is 100 percent to go or not," coach Pia Sundhage said yesterday. "And if she isn't, we have a tremendous backup goalkeeper."
Solo has said she lost some of her muscle strength during her 2-month run on "Dancing With the Stars," an appearance that capitalized on the U.S. team's popularity following last summer's World Cup.
Solo has played every minute of the Americans' three games at the tournament, but hasn't had to do much. The U.S. team has outscored its opponents 31-0, and Solo didn't have to make a save against Mexico.
And, on paper at least, a less-than-100-percent Solo or backup Nicole Barnhart should be more than enough to hold off Costa Rica.
On the men's side, Graham Zusi scored his first international goal in the eighth minute, and the United States beat host Panama, 1-0, in an exhibition game.
