MLS's experimental rule changes that cut time-wasting, sped up play are going global

• Ifab expected to adopt changes at meeting this weekend

• MLS added timed sub, off-field treatment rules in 2024

• New rules could make for faster play at the World Cup

Four years ago, MLS Next Pro implemented a pair of rules geared towards eliminating time-wasting. Now, just months ahead of the 2026 World Cup, MLS’s experimentation is set to be adopted globally. The International Football Association Board (Ifab), the sport’s rule-making body, is set to meet this weekend and is widely expected to adopt both changes.

The first of the two, commonly referred to as the timed substitution rule, forces a team to play a man down for a minute if a player takes longer than 10 seconds to leave the pitch. The second of the guidelines, dubbed the off-field treatment rule, removes a player from the match for a minute if they spend more than 15 seconds on the ground after an injury.
