"NFL brings back No. 0 jersey and clarifies personal foul penalties in 2023 rule changes."
The NFL has approved 17 playing rules, three bylaws, and three resolutions for the 2023 season, including the return of the No. 0 jersey, clarification on personal foul penalties, and a single date for roster cutdowns. Other proposed changes, such as making roughing the passer a reviewable call and allowing teams to go for it on fourth-and-20 instead of an onside kick, were not approved.
