The Florida State Boxing Commission and the Department of Business and Professional Regulations opened the preliminary investigation Oct. 8 after suggestions representatives for ProElite offered Petruzelli a chance to face Slice if he would agree to fight "standing up." Petruzelli was approached hours before the fight to fill in for Ken Shamrock, who sustained a deep cut during a workout earlier in the day and was deemed unfit to compete. Petruzelli would stop Slice 14 seconds into the fight.
