Jahvid Best -- NFL Should've BANNED Me From Draft ... Over Concussion History

Ex-Detroit Lions RB Jahvid Best says the NFL should NEVER have allowed him to enter the 2010 Draft ... because he had a well-documented history of concussions in college that made it UNSAFE for him to compete as a pro.

Best -- who was forced to end his NFL career in 2012 after suffering multiple concussions -- is suing the league ... and in the docs, he says the NFL should have saved him from himself.

In the docs, Best points out that during his college career at UC Berkeley ... he suffered at least 2 concussions, one of which made national news.

In fact, Best says the famous hit he took against Oregon State in 2009 became a viral video sensation because the play was so ferocious, many people thought he was killed on impact.

Best went on to declare for the NFL Draft and was cleared by the league. He was selected by the Lions in the 1st Round ... and during his brief pro career, suffered at least 2 more concussions that eventually ended his career in 2013.

In his lawsuit, Best pins the blame for his compromised health on the league ... saying, "The [NFL] allowed Best to be drafted and play despite his history of brain injury.”

Best says because of the NFL's actions ... he suffered "permanent and severe injuries to his brain."

He's suing the NFL and others for unspecified damages -- but it's clear he wants a fortune.
