Eric Dickerson holds the single-season rushing record of 2,105 yards set in 1984. Minnesota Vikings running back Adrian Peterson, who has 1,600 yards through 13 games, told Dickerson he should be nervous.
"I'm not nervous," Dickerson said, laughing to Mike Freeman of CBSSports.com.
Dickerson added: "I don't want him to break it," Dickerson said. "I'll be honest. I don't want to see it. If anyone ever broke it, and if my son played football, I'd want my son to break it. But that's it. No one else.
"Again, he's a phenomenal player and seems like a good dude. If a player was to break it, I'd probably want it to be Adrian, but I like having the record. I don't think it's going to be broken."
Dickerson said Peterson's next three games will be his toughest.
"As I got close to the record, teams got nastier and nastier," Dickerson said. "In one of my final games against Houston, they started saying and doing some things I didn't like, so I took it out on them.
"Defenses are going to say, 'This guy isn't setting the record against me.' They will be mad and do whatever it takes to stop him."
Dickerson added: "What he will see is that to set a mark like that, everything has to be perfect. The offensive line play has to be perfect. You can't fall behind badly. You can't get hurt. You can't have your players get hurt. You can't catch the defense on a day when they're playing perfect. Weather conditions have to be OK. Everything has to be perfect."
Peterson will have to average around 169 yards in his final three games against the Rams, Texans and Packers.
