Today’s Evolution update has a heavy emphasis on youth football around the country:

* The Waverly News reported on a Nebraska school system that quickly reacted to the state’s new concussion law. The Nebraska Concussion Act is forcing all state schools to take more concussion training and replace outdated equipment.

* In North Carolina, the Winston-Salem Journal reported how one area Pop Warner program is reacting to new guidelines handed down by the national organization.

* The Annapolis Capital Gazette wrote about how one group of doctors has started baseline testing for high school soccer players.

* In college football, The Times-Picayune updated us on Tulane safety Devon Walker, who had surgery Sunday night to repair his spine after suffering a broken neck the previous day against Tulsa. The surgery lasted three hours. While Walker had some movement in his limbs before the procedure, the doctors say they should know within 48 hours if he will be paralyzed.

* The Heritage Newspapers in Michigan wrote about how the Detroit Lions are taking concussions seriously, yanking rookie cornerback Bill Bentley when they weren’t sure if he had a concussion.
