John Sterling is in his 80s and has been calling N.Y. Yankee baseball games for decades. You would think he's seen it all but a foul ball in a weekend end game took him by surprise and wound up hitting him in the head - all while he was calling the play. Credit to him that he just kept going. 

He says he's fine, but who knew play-by-play could be so dangerous? Talk about a Bronx bombing.

There's the video of the incident here.
