Starting Quarterback Trent Edwards #5 of the Buffalo Bills suffers a concussion after getting hit by Strong Safety Adrian Wilson #24 of the Arizona Cardinals during the first half of their NFL Game on October 5, 2008 at Stadium in Glendale, Arizona.
There's a lot at stake this Sunday when the NFL begins its annual meeting in Phoenix, Arizona.
Thousands of players have filed lawsuits against the league because of traumatic brain injuries, and so in Phoenix the NFL may enact new rules to cut down on concussions. The league also announced this week it'll spend $60 million to research and develop new technology to prevent future injuries.
But there might be millions more to be had by companies that are springing up to offer their own equipment and products to the league.
