WWE legend Tammy Sytch just pleaded no contest to a felony charge of DUI causing death ... and she's now facing a prison sentence of up to a quarter of a century, TMZ Sports has learned.
The 50-year-old wrestling Hall of Famer was first hit with the count -- and seven others -- back in May 2022 ... after officials alleged she killed a 75-year-old man during a drunken car crash just two months prior.
Sytch had initially pleaded not guilty to all of the charges .
