(CNN) - On Sunday night, Fox aired "O.J. Simpson: The Lost Confession," a two-hour special that the network has been promoting as a must-see interview that was recently "found."
Originally shot in 2006, Simpson gives a "hypothetical" confession to the 1994 murders of his ex-wife, Nicole Brown Simpson, and her friend, Ron Goldman.
Simpson mentions a friend with him in this scenario, only identified as "Charlie," who he said gave him the knife.
"As things got heated, I just remember Nicole fell and hurt herself, and this guy kind of got into a karate (stance) thing, and I said, 'Do you think you can kick my (expletive)?'" Simpson said in the interview. "And I remember I grabbed the knife - I do remember that portion, taking the knife from Charlie.
"And to be honest, after that I don't remember, except I'm standing there and it's all kind of stuff around… blood and stuff around."
According to Fox, the lost tapes of Simpson's interview with then-HarperCollins publisher Judith Regan were recently discovered.
The interview was done in promotion of the book Simpson wrote with Regan, "If I Did It." It was never released by the book company.
