It's a couple days old, but I couldn't find anything on this here.  Apparently Denard Span didn't play this week because he retriggered concussion symptoms by rear-ending Danny Valencia on the way to the airport.

Denard Span rejoined the Twins’ lineup Wednesday after missing most of the past four months with a concussion, but he didn’t play in yesterday’s game and Rhett Bollinger of MLB.com reports that he re-triggered some of the post-concussion symptoms by rear-ending teammate Danny Valencia while driving to the airport.

Seriously:

Span was following Valencia from Target Field to airport and ran into his car in stop and go traffic. Valencia’s fiance was driving. Span and Valencia were able to joke about the accident, but both are dealing with whiplash and headaches.

The story would be pretty funny if Span’s health status and the Twins’ entire season weren’t so depressing, and the fact that Justin Morneau still isn’t right physically 15 months after suffering his own concussion last year only adds to the sadness.
