The NFL updates its replay rules to let head coaches assign a designated staff member to throw the red challenge flag and initiate an instant replay challenge. Under the change, the challenge can be started by the head coach or a pregame designated designee.

Previously, only the head coach could carry and throw the red flag onto the field to stop play for a review. Multiple outlets note the league’s current instant replay framework dates to 1999, when the head coach-only process was established.

The reports describe the change as starting this season and tied to Rule 15. The rule book language highlighted by Yahoo indicates the designated person can throw the red flag onto the field before the next legal snap or kick, matching the timing requirements for when a challenge must be initiated.
