Oklahoma State head coach Mike Gundy is once again being accused of using a racial slur during a game in 1989.
Former Colorado linebacker Alfred Williams said at the time that Gundy - who was the Oklahoma State quarterback when the two teams squared off in 1989 - called him the N-word.
Gundy denied that such an incident occurred, but Williams said on Wednesday that he remembers hearing the former quarterback use the racial slur twice, once before halftime and again during the second half of Colorado's 41-17 win, according to The Oklahoman's Jacob Unruh.
"I remember that it was the first time that the University of Colorado beat Oklahoma State while I was there," Williams told Unruh. "It was a big win. It really was a big win.
"And I remember Mike Gundy called me the N-word. That's what I remember."
Williams said he has "at least 20 people who will vouch for what happened that day."
In its game story from that day, The Daily Oklahoman addressed the accusations, which Gundy said were "just not true."
"I'm a little upset, because after 31 years I finally saw the story published in your papers out in Oklahoma," Williams said. "That was the first time I saw some of the responses to what I said."
He added: "I want an apology from him and I want to see him have some growth."
Gundy responded to a separate controversy Monday following Oklahoma State star running back Chuba Hubbard's threat to stop representing the school after the head coach was photographed wearing a One America News T-shirt.
