The star linebacker for the Carolina Panthers, Luke Kuechly, missed the last five games of the 2016 NFL season after he suffered a concussion.
So this season, he’s trying on something new: the Q-Collar, an experimental product developed by Q30 Innovations that has been studied and shown to decrease the risk of brain injury, according to The Charlotte Observer.
The collar is a thin band whose ends press lightly against the jugular vein, decreasing blood flow out of the head, according to a June 2016 news release on the Q-Collar.
