Sean Morey's 10-year career as a special teams ace came to an abrupt halt in 2010 when "post-concussion syndrome" forced his retirement. Even though he was no longer playing, he told Sports Illustrated that he felt like he had just "made six or seven tackles."
His experience led him to donate his brain to the CSTE. "One of the most profound actions I can take personally is to donate my brain to help ensure the safety and welfare of active, retired, and future athletes for decades to come." Morey said in a 2009 written statement.
In 2014, Morey was part of a group of seven plaintiffs, who filed a formal objection to the $765 million NFL Players' Concussion Injury and Proposed Settlement calling it a "lousy" deal which didn't offer enough, prior to formal approval of the agreement. The settlement was meant to resolve concussion-related lawsuits and fund medical exams, concussion-related compensation and medical research.
The appeal failed, but only after the NFL removed the $675 million cap (part of the $765 million settlement) on damages in response to a federal judge questioning if the figure was enough to cover an estimated 20,000 retired players.
