Add one more to the list: A gnarly outbreak of herpes gladitorum on the York College of Pennsylvania's wrestling mat.
(Disclosure: During my high school years, I swam in the YCP pool. I've never wrestled anyone.)
Three college wrestlers filed a lawsuit against their coaches and the school, alleging the team violated NCAA rules by knowingly letting guys with herpes engage in full-contact practices. The virus spread to the three plaintiffs, and now they want at least $50,000 in damages.
