Story veered off before colliding with Dahl, but it appeared Ciriaco's knee slammed into Dahl's head and upper body. Dahl remained on the ground for some time, but he walked off the field on his own. According to Yahoo! Sports, Dahl likely has a concussion, a broken rib and a ruptured spleen that requires surgery.
Dahl, MLBPipeline.com's No. 54 overall prospect, is in his first year at the Double-A level. The 21-year-old, a first-round pick in the 2012 Draft, was hitting .269/.296/.379 with three home runs and 16 RBIs in 44 games.
