|Danley was hit in the head Monday night.|
In 2009, Danley took a broken bat from Hank Blalock to the head in Texas, requiring a stretcher to be brought onto the field. After the game, was diagnosed with a mild concussion.
In 2012, Danley was struck in the groin by a directly pitched ball in the dirt, remaining in the game.
In May 2013, Danley sustained a concussion.
Because Danley has suffered multiple traumatic brain injuries in the past, he is more susceptible to concussion, though in regards to the present, he is listed as day-to-day.
