NFL Searching for Concussion-Preventing Helmets

NEWYou can now listen to Fox News articles!

The NFL is searching for safer helmets and considering offseason rule changes to provide more protection from concussions.

And Congress is still on the case, too.

The House Judiciary Committee has scheduled a hearing at Detroit's Wayne State University School of Medicine tomorrow.

An NFL spokesman says most players are still wearing helmets designed in the '90s, and that the league wants more research done.

However, one researcher who recently conducted crash-dummy tests on five manufacturers' helmets for the NFL worries about how the data is used. He's concerned somebody might reach an incorrect conclusion that because one helmet performs better than another there's less likelihood of injury with that helmet.

David Halstead of the Southern Impact Research Center is particularly concerned the study will be construed by high schools or youth leagues as recommending a particular helmet.
