McCann has a .264 batting average with 10 home runs and 39 RBIs in 74 games this season. He also was placed on the injured list in April due to a right hamstring injury.
McCann, a seven-time All-Star, returned to the Braves this off-season after stints with the New York Yankees (2014-16) and Houston Astros (2017-18). He spent the first nine seasons of his MLB career with the Braves before leaving for New York.
The Braves recalled catcher Alex Jackson from Triple-A Gwinnett in a corresponding roster move. Jackson, 23, is hitless in 10 at-bats across three games for Atlanta in the 2019 campaign.
