Atlanta Braves rookie outfielder Austin Riley has a partial tear of the lateral collateral ligament in his right knee and will undergo further evaluation to see if surgery is needed, manager Brian Snitker told reporters Thursday.
Riley was injured in the weight room pregame on Tuesday in Minneapolis, according to Snitker.
The Braves put the 22-year-old Riley on the 10-day injured list Thursday. He is expected to be seen by Dr. James Andrews on Monday to further determine the nature of the injury.
Riley is hitting .242 with 17 home runs and 45 RBIs in 66 games since his mid-May call-up from Triple-A Gwinnett, where he smacked 15 home runs in 37 games. Riley, a first-round pick by the Braves in 2015, had been considered the team’s top prospect among position players.
He has slumped lately, hitting .160 (12-for-75) since June 30.
The team recalled rookie right-hander Jeremy Walker from Triple-A to take Riley’s roster spot.
Walker, 24, has pitched three scoreless innings in three appearances for the Braves this season. He was a combined 2-6 with a 3.01 ERA and seven saves in 27 appearances (one start) for Double-A Mississippi and Gwinnett.
