Football players are wearing a device called the Q-Collar around their necks. The Q-Collar is a medical device that is intended to protect athletes brains during head impacts by compressing against the jugular veins in the athletes neck, increasing the volume of blood in their skulls blood vessels. The increased blood volume then creates a tighter fit of the brain inside the skull, which can reduce the "slosh" movement and prevent brain injury. The Q-Collar is produced by a company called Q30 and was authorized by the US Food & Drug Administration in 2021. It is not intended to prevent concussions or serious head injuries, and it should not be used by athletes with certain conditions. Some notable NFL players who wear the Q-Collar include Tony Pollard, Dalton Schultz, Drue Tranquill, Shaq Thompson, Taylor Rapp, and Boston Scott.
