Freeman's kneecap popped out of place Tuesday attempting to field a low throw during an infield drill. The team says the knee is stable and he had a similar injury in the minors two years ago. Freeman missed about a week the last time.
The Braves already are dealing with pitcher Tommy Hanson sustaining a concussion in a wreck and utility infielder Jack Wilson being out up to six weeks with a strained calf muscle. Also, pitcher Tim Hudson will probably miss the first month of the season recovering from back surgery.
Freeman was runner-up for NL Rookie of the Year after hitting .282 with 21 homers and 76 RBIs.
