Considering his current stance on concussions, the 38-year-old Davis might have stepped out of bounds a few more times.
Davis, who was inducted into the South Carolina Athletic Hall of Fame in May, has experienced lapses in his short-term memory, forgets time spent with his children and will sometimes record conversations to recall certain details, Fenno reported.
"Looking at the results, and they're not that good," Davis said of a visit with a neurologist. "I need to get special treatment, further treatment to try and get it taken care of ... A lot of things scare me a whole lot, and it bothers me because there isn't no telling what day I'll forget everything."

Davis, who last played in the NFL in 2006, likes the steps the league is taking, but does not want former players to be forgotten.
"I just want to be fair," Davis said. "Football is a contact sport. We all know that. It has its consequences. But the thing is that we were put in situations where if you're not on the field, you won't make this team.
Davis said he would not keep his son from playing the game.
"I will tell him the cons and pros of it. Everything he sees," Davis said. "I sit him down every day and say, 'These are the things that can possibly happen to you.' "
