It's suspicious, but at the same time, it's happened enough over the past few years that it comes as no surprise. My current money for Prior's freak injury du jour is on: "Mark is walking along in Grant Park in June when he passes under a tree. At this moment, a squirrel falls out of the tree and lands on Prior's head. The squirrel freaks out, then claws and bites Prior's face and neck. Doctors diagnose Prior with rabies, causing Prior to miss the rest of the season." I got 10-1 odds on it. :D
