DETROIT -

Jahvid Best stormed out of the gates as an explosive running back in 2011 when the Detroit Lions drafted him in the first round, but then came the injuries -- including concussions.

Now, Best is suing the NFL, claiming they should have done more to protect him and others from potentially devastating injuries.

Best had a strong rookie season, but played just six games in his second year and was released by the Lions prior to the 2013 season. He suffered at least five concussions in his football career, two at the University of California and three with the Lions. His 90-page lawsuit targets the NFL and Riddell, the maker of NFL helmets.

“The NFL was aware of the evidence and the risks associated with repetitive traumatic brain injury but deliberately ignored and actively concealed the information from the plaintiffs and all others who participated in organized football at all levels,” the lawsuit states.

For the past several years, the NFL has been in constant litigation over concussions, having been sued by nearly 5,000 former players.

Does the NFL promote violence in the game? Should the league do more to warn and educate players? Those are just some of the questions that will now go before a court.
