Corey Brown underwent surgery Wednesday to have a staph infection removed from his right knee. Brown won't return to action this season but should be back to 100 percent by the start of spring training next February. The 25-year-old outfielder slugged 14 homers in 462 plate appearances this year at Triple-A.

Corey Brown (staph infection) is likely to be shut down for the rest of the season. "The knee wasn't progressing like it should," Nationals manager Davey Johnson said. "The orthopedic surgeon said they were going to have to open [the knee up] a little bit to get the infection out. So he will not be joining us on this trip [to New York." Brown has been hitless in three at-bats for Washington since being promoted last week.

Nationals manager Davey Johnson hopes Corey Brown (staph infection in his knee) can return later this week. Brown did not travel with the Nationals on Sunday under doctor's orders. "The doctors felt that rather than go on the road trip, maybe have him see a doctor," Johnson said. "Instead of getting better, it could get worse. I think there was a concern that it could turn into a staph infection. We just kept him in Washington to be on the safe side. Hopefully today or tomorrow, he could be all right and rejoin the club." Brown was promoted to the major leagues last week after batting .235/.326/.402 with 14 homers in 462 plate appearances for Triple-A Syracuse. He has only three at-bats so far for the Nats.

Nationals recalled OF Corey Brown from Triple-A Syracuse. Brown, who was acquired from the Athletics in the Josh Willingham deal, batted .235/.326/.402 with 14 homers, 39 RBI and a .727 OPS over 462 plate appearances at the Triple-A level this season. Roger Bernadina is out for a week after slicing his hand, so the 25-year-old Brown will provide some center field depth.
