So, are athletes suffering more concussions, or—to borrow an argument from the field of autism—have trainers simply gotten better at diagnosing them?

Whatever. There’s a virtual epidemic of concussions these days, and no wonder—given all the pressure football has faced over the long-term effects of head injuries on the likes of the Bears’ Dave Duerson.

The White Sox’s Paul Konerko came down with a concussion last week, and was placed on the seven-day disabled list—newly created specifically to address head injuries.

Paulie’s concussion symptoms are said to be mild, but it gives a fan pause, considering the extended time off they recently caused the Blackhawks’ Jonathan Toews and the Minnesota Twins’ Justin Morneau, who pretty much crashed the franchise with his long-term recovery.
