Solo has had a variety of issues in the past, ranging from clashes with a coach to social-media battles with former players to her arrest on domestic-assault charges last year. (Those charges were later dropped.) A more serious incident occurred in January, when Solo was suspended after she and her husband, the former N.F.L. player Jerramy Stevens, were stopped by the police while driving one of the team’s vans and Stevens was arrested on a charge on suspicion of driving under the influence.

Solo said she addressed her teammates just before leaving camp to begin her suspension and, since rejoining the team, has done her best to slip back into the fold.

“It’s not easy for Hope to talk about her feelings, and for me, that’s a step in the right direction,” Wambach said. “It’s not an easy road that she’s been on.”

Wambach added: “I think once something like this happens you can see a genuineness in someone.”

For the moment, it seems that everyone — teammates, coaches and officials — is supporting Solo, a stance that is surely bolstered by the fact that she is still regarded by many as the best women’s goalkeeper. There is no question that the United States team is far better with her than without her. Now that she is back, she must help solidify a defense that has had problems with consistency in recent games.

“The sooner I can get her in with her back line, the better,” Ellis said.

Christie Rampone, the veteran defender and captain, is out because of an injury. Her presence would surely help settle the unit, but the United States was victimized by poor marking in its loss to France last month and was again on Wednesday. Norway’s goal came just before halftime when Ada Hegerberg was left alone for a sharp header from a few yards out. The goal was frustrating for the United States, which had controlled the game’s pace to that point.

The second half was better, and the United States tied the score on Lloyd’s laser from outside the penalty area. The goal was eye-popping; after a quick turn, Lloyd let fly with a left-footed blast that the Norwegian goalkeeper watched helplessly.
