Freeman may miss two weeks with achy knee

LAKE BUENA VISTA, Fla. -- Braves first baseman Freddie Freeman might be sidelined over the next two weeks as he rests a right knee injury that he suffered during Tuesday morning's workout at ESPN's Wide World of Sports Complex.

Freeman's right knee popped out of place as he was attempting to pick a low throw out of the dirt. The 22-year-old first baseman limped off the field immediately and was still struggling to walk as he made his way to a photo shoot early Tuesday afternoon.

"I was just doing pick drills and the knee gave out," Freeman said. "The kneecap went this way and I came back in. When I did this when I was playing in Triple-A, it took me two weeks. So that is what we are going on."

The Braves have diagnosed Freeman's injury as a subluxed right patella and revealed his knee is stable. The club believes he will miss one to two weeks.

While he was in obvious discomfort, Freeman did not seem worried about the possibility that he will need more than just a couple weeks of rest. His right knee had not given him any problems since he had suffered a similar injury while playing for Gwinnett in 2010.

"When I did it in 2010, I thought I could come back after a week," Freeman said. "But they're obviously going to be cautious with me."

If Freeman misses two weeks, he could return in time to play the final two weeks of the exhibition season. His absence will likely provide Eric Hinske and Ernesto Mejia a chance to get plenty of playing time at first base during the Grapefruit League season's first two weeks.

Freeman is coming off a memorable rookie season during which he hit .282 with 21 home runs and a .448 slugging percentage.
