Running onto the field in the middle of a game may seem like a fun thing to do, but it usually ends in pain thanks to the security guards that patrol the field.
Security guards have one job to do in situations like that, get the fan off the field so the game can continue and if they have to absolutely rock said fan in order to make that happen, they won't hesitate to do so.
Wednesday night in Boston, we saw that first hand as a Red Sox fan stormed the field and got crushed by a vicious blindside hit from a security guard.
And another angle for your viewing pleasure (you're welcome): This right here is why you never storm the field. Nothing good ever comes out of doing so and what happened to this Red Sox fan is usually how every one of these situations end. (H/T: FTW)
