FORT LEAVENWORTH, Kan. (AP) Former Kansas City Chiefs players, including Pro Football Hall of Fame linebacker Willie Lanier, are heading to Fort Leavenworth for talks with Army officials on traumatic brain injuries. Wednesday afternoon’s meeting at the post is part of an Army-NFL partnership on treating and preventing head injuries in both organizations. Lanier, who played from 1967 through 1977, serves on an NFL player safety panel studying ways to make the game safer. Lanier suffered numerous concussions in his early playing days before converting to a padded helmet and changing his tackling technique. The military has been looking at the impact of traumatic brain injuries as soldiers return from combat.
