After Bryce Harper ran full-speed into the Dodger Stadium wall on Monday, he "had no idea where he was." He was nauseous all day yesterday, and couldn't play. He's expected to miss tonight's game as well. But he's totally fine, the Nationals would like to assure everyone. Just a little sore.

In a new study published today in the Journal of Neurosurgery, a group of scientists proved, seemingly, that modern football helmets are better than old leather ones. Thanks, guys. What is more notable, however, is that this batshit crazy device is how the data was gathered.

The competition to study the brains of former NFL players is ugly; almost as ugly as the league's decades of denying that concussions lead to long-term health issues.

A brain-damaged Colorado high schooler has won a $3.1 million judgment against helmet-maker Riddell, claiming the company failed to adequately warn users of the dangers of concussions.
