Former Lions running back Jahvid Best is suing the NFL, Riddell and Easton-Bell Sports in relation to concussions he sustained in his playing days, according to a report from ESPN.com.

Best had a promising career that was cut short due to multiple concussions throughout his NFL career. He also had a major concussion during his final season in college at California.

"The purpose behind the lawsuit, there's a number of requests of release in the lawsuit," Best's attorney Bret Schnitzer said, via the ESPN article. "One of them is to set up a medical fund for Mr. Best in order to deal with future medical conditions out of this concussion syndrome."
