The Braves announced that the first baseman was removed from the game because of right elbow soreness.
The four-time All-Star has been a big part of Atlanta’s success in 2019.
Freeman, 30, is having a career year and is slashing .303/.393/.568 with 38 home runs and a team-leading 117 RBIs.
Atlanta entered Friday atop the National League East with a 91-57 record.
Without Freeman, a 2018 Gold Glove Award winner, the Braves would likely see a decline offensively and defensively. They’ll hope his condition is nothing serious.
Freeman was hitless in two at-bats against Washington before exiting the contest in the bottom of the fourth inning.
