Atlanta Braves rookie outfielder Ronald Acuna Jr. has a sprained ACL and contusion in his injured left knee and will be placed on the 10-day disabled list.
The Braves announced the nature of the injury Monday, less than 24 hours after Acuna's leg buckled awkwardly as he raced to beat out an infield single during Atlanta's game against Boston.
Acuna also has a lower back contusion and will be evaluated at the end of his 10-day stint on the DL, according to the Braves.
Atlanta has not officially made the move to place Acuna on the DL.
