CARSON, California (AP) — Los Angeles Galaxy forward Landon Donovan tested positive for what was believed to be swine flu, and his teammates are taking precautions.

Donovan was to be evaluated by a doctor on Friday and Saturday, the team said. His status for the Galaxy’s game against Seattle on Saturday in Major League Soccer remained unclear.

“It certainly depends on how Landon feels and what the doctors tell me,” Galaxy coach Bruce Arena said on Friday.

Donovan did not practice on Friday after playing all 90 minutes for the United States in a 2-1 loss to Mexico in World Cup qualifying on Wednesday in Mexico City.

The United States Soccer Federation said Donovan joined the national team on Aug. 9 in Miami, three days before the game. It also said that no other players expressed or showed signs of flulike symptoms while in camp.

“Even Landon said it hasn’t hit him as hard as the normal flus have hit him,” Galaxy spokesman Justin Pearson said.

In a statement, the federation said Donovan tested positive for the influenza A virus, which was presumed to be the H1N1 strain known as swine flu.

“We had the flu run through the team last week in Boston,” Arena said. “We took the necessary precautions. We had a couple of staff members out a couple of days and on medication.”

All Galaxy players and support staff who encountered Donovan have been informed to take medication. Roughly half the players on the U.S. team are rejoining clubs in Europe, while the rest return to MLS teams.

Also missing Galaxy practice on Friday were David Beckham and Chris Birchall, who played on Wednesday for England and Trinidad and Tobago, respectively. They, along with Donovan, received the day off, said Arena, who added that nobody other than Donovan was sick.
