The connection between football and concussions is a hot button issue across the country.
Last year, many former professional football players came forward about the lingering effects of head injuries.
Now, the very thing that is made to protect their heads from injuries is coming under fire.
A new study of football helmets claims they don’t always do a good job of protecting the head against a concussion.
Florida State researchers did more than 300 tests on helmets using a crash test dummy.
They found many helmets in use today do little to protect against hits to the side of the head.
Some brands offered some protection against concussions but did poorly on other tests.
However, football helmets are still protecting users from other dangers.
They reduced the risk of skull fractures significantly by 60 to 70 percent.
