NCAA set to study if multiple football helmets spur injuries

The NCAA’s football oversight committee will meet this week in Indianapolis and is to begin studying whether multiple helmets could lead to more concussions and serious head and neck injuries.

Oregon football players used three helmets last season that were mixed and matched with myriad uniform combinations.

Last year, Oklahoma State players were given five helmets. Virginia Tech and Arizona State players had four.

In the NFL, this will be the fifth season in which players may wear only one helmet.
