Albert Lewis and Art Still are among nine former Kansas City Chiefs players who have joined a lawsuit that contends the team hid the risks of permanent brain injuries from repeated concussions.
Five former players filed the initial suit against the Chiefs this month, saying the team ignored decades of scientific research indicating repeated head trauma causes permanent brain damage. In the amended suit filed Saturday in Jackson County Circuit Court, the plaintiffs said Arrowhead Stadium’s artificial surface contributed to the head injuries.
Also joining the lawsuit were Dino Hackett, Todd McNair, Fred Jones, Tim Barnett, Walker Lee Ashley, Emile Harry and Chris Smith, along with the wives of several of them.
The concussions happened between late 1987 and early 1993 when there was no NFL collective bargaining agreement in place.
