24 hours: Game officials must be in the city in which they are working that week. If severe weather is anticipated, officials should arrange to arrive earlier. The crew meets the day before kickoff to reviews both teams’ tendencies and any weekly points of emphasis from the Officiating Department.

18 hours: Visiting teams traveling by airplane must be in the game city.

4 hours: All local game day assistants must arrive at the stadium and begin setting up their respective equipment/systems.

3 hours: Sideline and coaches’ booth technicians test the wireless equipment in each bench area and wired equipment in each coaches’ booth. (If the coaches’ communications system (C2C) or Coach-to-Player communication system (C2P) for one team suffers a total system failure at any point during the game, the other team’s system will be shut off until functionality is restored to the affected team). C2P technicians test and distribute C2P equipment to each club’s equipment manager. The injury video review system operator distributes a case containing fully charged radios to the visiting club’s athletic training staff at the entrance to the visiting locker room. Field technicians report to the stadium and set up field monitor systems.

2 hours, 30 minutes: The home club delivers the wireless microphone to the referee.

2 hours, 15 minutes: Each club provides 12 primary and 12 backup like-new, properly prepared Wilson official NFL footballs to the Referee for inspection. Additionally, one representative from each team can inspect and prepare the kicking balls that the officials received directly from Wilson Sporting Goods.

2 hours: C2P technicians conduct final C2P system testing with each club’s equipment manager. Sideline and coaches’ booth technicians conduct final testing on the entire C2C system. Field technicians conduct replay official equipment check at each of the field monitor stations.

2 hours: The injury video review system operators distribute radios to the local league-appointed unaffiliated neurotrauma consultants, airway management physician, emergency response physician, and AT spotters. The AT spotters — located in a stadium booth — are certified athletic trainers that help each team’s medical staff spot potential concussions or other head and neck injuries. A neurotrauma consultant on each sideline helps with assessing concussions, and one in the AT Spotter booth helps identify potential head injuries. An emergency response physician and an airway management physician (certified in rapid sequence intubation), stand between the 25- and 30-yard lines on either sideline near paramedics who have coordinated arrangements for immediate transport via police escort or medevac helicopter to a predetermined hospital.

2 hours: Game officials test the wireless microphone units (primary and backup). A member of each club’s sideline staff, designated as the liaison with the referee, keeps spare batteries for the units should they need to be replaced. The referee meets with stadium personnel at the 50-yard line of the home team’s bench area to check all necessary electronic equipment.

2 hours: All printing stations and Microsoft Surface tablets must be in place on the sidelines. These are used by the coaches for the printouts or the Sideline Viewing System, which lets them review images of opposing team coverages and schemes during play. The league office provides a four-person “purple hat” crew to set up the equipment; this crew will also take it down after the game ends.

2 hours: The visitor’s half of the field must be clear at least 120 minutes prior to kickoff, unless the field is tarped in accordance with league rules.

Network sideline security meeting: Approximately two hours prior to kickoff, the local security representative, field security representative of the stadium, NFL Football Operations Representative, National Game Representative (if applicable), home and visiting PR representatives, and the television network will meet to go over sideline restriction rules for network crews.

100-minute security meeting: One hour and 40 minutes prior to kickoff, the Referee, league and club security representatives, NFL Football Operations representative, stadium security and the local senior public safety official in charge of the field meet to review procedures for responding to an emergency situation before, during or after the game.

This critical meeting includes the review of broadcasting policies and procedures, exchange of Game Day Administration Reports (which includes a club’s inactive list, players designated to have C2P components in their helmets, and players/coaches wearing microphones), synchronization of watches and review of the pregame schedule, such as when each team must leave its locker room.

Field Emergency Preparedness Meeting – 90 minutes prior to the scheduled kickoff, there will be a meeting of the on-field emergency medical services (EMS) crews, the airway management physician (AMP), and the emergency response physician (ERP). The purpose of this meeting is to perform checks on all emergency supplies and equipment to ensure all are present and in working order, review all emergency medication, review roles, responsibilities and procedures for responding to an on-field emergency, egress routes for hospital transport, and designated trauma center/specialty hospitals that will be used for different types of emergencies.

90 minutes: The grounds crew must have the tarp completely removed from the field if the field was covered due to precipitation. If the stadium has a retractable roof and/or wall, the home club notifies the referee or on-site NFL Football Operations representative whether the roof and/or wall will be open or closed during the game. An open roof or wall can be closed after this point only under certain conditions, including precipitation or if hazardous conditions, such as lightning, endanger people in the stadium.

60-Minute Medical Meeting — 60 minutes prior to the scheduled kickoff, there will be a medical meeting outside of the Officials’ locker room. The head team physicians, head athletic trainers, AT spotters, UNCs, paramedic crews, airway management physician, emergency response physician, NFL Football Operations representative, and the Referee will meet to review medical procedures and protocols, verify the location of medical equipment and test communication equipment.

60 minutes: When applicable, the stadium roof and/or wall must be in its designated opened or closed position, and all lights must be turned on in domed stadiums or stadiums with a retractable roof in the closed position.

60 minutes: C2P communications technicians must be present in the bench area of each club. They remain there throughout the game. Field technicians prepare monitor stations for an equipment check by the Referee.

60 minutes: The official team warm-up period begins. Each team must warm-up on its designated half of the field, as designated in the NFL’s Game Operations Manual. During warm-ups, a league uniform inspector checks every player to ensure that all uniforms conform to league specifications.

35 minutes: The Referee checks his microphone with the television network broadcasting the game.

20 minutes: Earliest a visiting team can be required to end its warm-ups, absent a leaguewide obligation or event being conducted on the field during the warm-up period.

Within 20 minutes, the schedule varies slightly depending on the game time, the network broadcasting the game and home team production elements.
