The Atlanta Braves placed catcher Travis d'Arnaud on the seven-day concussion injured list Sunday.
The 34-year-old veteran was injured in a collision at the plate with San Diego's Rougned Odor in Saturday's 4-1 loss to the Padres.
"He's had a few of them," manager Brian Snitker said of d'Arnaud's history of concussions. "That's nothing to mess around with."
The Braves recalled catcher Chadwick Tromp from Triple-A Gwinnett in a corresponding move.
Through eight games, d'Arnaud is batting .333 with three doubles and five RBIs.
An All-Star in 2022, d'Arnaud is a career .253 hitter with 97 homers in 719 games with four teams.
Tromp, 28, appeared in one game with Atlanta last season and went 3-for-4 with two doubles and three RBIs.
