The Los Angeles Dodgers saw a startling injury in their first spring training game as a key starter collapsed on the field.

Cubs infielder Michael Busch sent Miller’s 80 mph pitch right back at Miller, nailing the 25-year-old righty in the side of the head and sent him crumbling to the ground. Miller immediately grabbed his head and attempted to compose himself as his teammates approached to check on him. The Dodgers pitcher walked off the field under his own power.

During the first game of spring training on Thursday, Los Angeles Dodgers pitcher Bobby Miller was struck in the head in the third inning after Chicago Cubs first baseman Michael Busch sent a 105.5 mph line drive his way.
