Overview
- The league revised Rule 15, Section 1, Article 1, and on Monday confirmed that the head coach or the head coach’s pregame challenge designee can start a challenge by throwing the red flag.
- Teams that use the option must notify the officiating crew of the designee before the game begins and the change is voluntary for every club.
- All standard challenge mechanics remain the same: teams get two challenges per game, can earn a third if one is overturned, and lose a timeout for an unsuccessful challenge.
- The tweak was made during routine summer rulebook adjustments that do not require an owners’ vote and follows a 2025 season that featured 151 coach challenges.
- The move may reduce heat-of-the-moment flag throws and shift some sideline duties to assistants, though many head coaches are expected to retain strong control over the actual challenge decision.
