Los Angeles standout Landon Donovan limped off with a leg injury during the Galaxy's 2-1 Major League Soccer loss to Real Salt Lake, creating doubt whether he will be available for the United States' upcoming World Cup qualifiers

CARSON, Calif. — Los Angeles standout Landon Donovan limped off with a left-knee injury with about 10 minutes left in the Galaxy’s 2-1 Major League Soccer loss to Real Salt Lake on Saturday.

The injury creates doubt whether Donovan will be available for the United States’ World Cup qualifiers at Antigua & Barbuda on Friday and against visiting Guatemala on Oct. 16.

The extent of the damage wasn’t known.

“We have to get it worked out. … It didn’t feel good,” Donovan said.

The 30-year-old midfielder missed last month’s qualifiers against Jamaica because of a hamstring injury.
