Atlanta Braves phenom Ronald Acuna Jr. suffered what looked like a gruesome injury on Sunday while trying to run out a single in the seventh inning during a 7-1 victory over the Boston Red Sox.
Acuna appeared to hyperextend his left knee before tumbling to the ground down the first base line.
As a warning, the video is a bit graphic.
Acuna was somehow able to walk off the field, despite a pronounced limp, after being immediately tended to by team trainers. The Braves later announced he was taken out of the game with knee and lower back pain.
