In 1996, he stepped up to the heavyweight division, but lost by knockout in five rounds to Evander Holyfield and quickly retired. Czyz fought one last time in 1998, losing by second-round TKO to South African Corrie Sanders. Czyz continued doing color commentary for Showtime, but was let go after pleading guilty to his fourth drunken-driving offense in six years after being caught speeding in Readington Township, New Jersey. Czyz's case received a lot of attention as he was a multiple repeat DUI case, and was a driver behind the NJ Assembly revisiting its legislation. Czyz, who was a Raritan Township, New Jersey resident at the time, was given a six-month license suspension for each of his three drunken driving convictions in 1998, 1999 and 2000. It was discovered that he was sentenced improperly as a first-time offender after his fourth arrest, which occurred in February 2003 in Readington Township, where he was caught driving with a blood-alcohol level of 0.14 percent. The state limit at that time was 0.10 percent.
