HMM, Morneau got his first concussion (in baseball) when he was beaned in the BB box. The second sliding into 2nd base, and a third turning to catch a pop-fly at 1B--(somewhat similar to what happened to Koskie though he was at 3B). So, your fears are wasted--injuries can happen anytime, anyplace. Players have been hit by balls and bats in the dugout too!
