VAR & Substitution Rules

Substitution protocols remain at five substitutes per team, used across up to three stoppages, with a sixth allowed in knockout extra time. Teams can also replace a starting player before kickoff in case of medical incapacity without penalty

• League phase: September 2025 – January 2026, followed by knockout phase starting February 2026
