Atlanta Braves reliever Jackson Stephens has been placed on the seven-day injured list with a concussion after he was hit in the side of the head by a line drive Friday night.

Stephens had walked off the field in the ninth inning against the St. Louis Cardinals but was taken to a hospital for testing.

"He's aware and everything, but he's going to have to go to the hospital and get some tests," Braves manager Brian Snitker said after his team's 11-4 victory.
