With U.S. coach Jurgen Klinsmann scheduled to announce Monday his U.S. squad for the two upcoming World Cup qualifiers, the last thing he needed to hear about was a possible knee injury to key midfielder Landon Donovan.

But that’s exactly what happened Saturday in the Galaxy’s disappointing 2-1 loss to Real Salt Lake in Carson (more on that later), with Donovan forced to come out of the game 10 minutes from time after landing on Real Salt Lake defender Jmison Olave as he attempted to go past him down the left flank.

“It didn’t feel good,” Donovan said after the game, adding that he did not hear a “pop.”

Donovan said he would be examined as soon as possible. When asked if the injury would take him out of the U.S. squad for the games against Antigua & Barbuda Oct. 12 and Guatemala four days later he said that was “TBD” (to be determined).

Donovan has had more than his share of injuries since Klinsmann took over as U.S. coach, missing several crucial games.
