Atlanta manager Fredi Gonzalez made the annoucement Tuesday before Atlanta played the San Diego Padres.
Uggla and Gonzalez had a conversation before the game. Uggla says he didn't agree with the decision.
Uggla, who signed a five-year, $62 million contract after the Braves acquired him in a winter trade with Florida, has just four hits in his last 47 at-bats - dropping his season batting average to .178.
Gonzalez replaced Uggla with Brooks Conrad, who will play second base and hit eighth.
Uggla is coming off a career season with the Marlins, batting .287 with 33 homers and 105 RBIs.
For Atlanta, has seven homers, 16 RBIs, a .322 slugging percentage and a .246 on-base percentage.
