Concussions certainly are not new in sports and neither is talk about how to diagnose and handle an athlete who has suffered trauma to the head or brain.
What is new is the University of Nebraska's development of a sideline tool to diagnose a concussion.
Nebraska's new Center for Brain, Biology, and Behavior has developed a cap with electrodes that acts as a functioning MRI on the sidelines. The idea is that within 10 minutes, medical personnel will be able to determine if an athlete has suffered a concussion.
The hope is that the cap will allow a team's medical staff to analyze the player's brain waves and determine if he sustained a concussion and the severity, the center's director, Dennis Molfese, told CBSSports.com.
"There has been great concussion research that's been going on for decades," Molfese said. "It's disconcerting to realize just how little we really know."
The device should be ready for use "within one to two years," and eventually could spread to other areas of health care, Molfese said.
Currently, medical staff will take a player to the sideline or locker room to conduct a procedure to determine if a concussion has been suffered. The procedure involves only asking questions and having the players perform hand-eye coordination tests.
