As fans prepare for Lambeau Field’s first preseason game Saturday night, the Packers are set to welcome fans to Lambeau Field and are reminding game attendees about the stadium’s exit and re-entry policy.

Beginning four hours prior to kickoff, no exiting and re-entry will permitted. Guests that leave the stadium after entering will not be allowed to re-enter. The Lambeau Field Atrium, Packers Pro Shop, 1919 Kitchen & Tap and Packers Hall of Fame will only be open to ticketed guests at 11 a.m. on Saturday, and guests will not be able to exit and re-enter after 3 p.m.

Saturday’s game is the annual Midwest Shrine game. Since its inception in 1950, the game has raised more than $3.5 million for the Midwest Shrine’s burn centers and hospitals. Janine Brass will be performing the national anthem. Brass is a former patient of the Shrine Hospital and has been a fan favorite at the Shrine game for many years.

Available for fans to use at Saturday’s game is free, enhanced Wi-Fi service, installed during the past offseason at Lambeau Field. Fans can connect to the “LambeauField” Wi-Fi network through the settings on their mobile devices, and those with cell service through Verizon Wireless can connect to Verizon’s own Wi-Fi network in the stadium and enjoy enhanced cellular coverage. Those with service through AT&T can also expect improved coverage in Lambeau Field.

During halftime, the High School Quarterback Challenge competition on the field will feature players from Rice Lake High School and Superior High School.

Saturday’s game will recognize USA Football Month, as the Packers have invited four teams from Racine Youth Sports to play on the field during halftime, with players ranging in age from 9 to 11. In addition, the Packers have donated more than 3,300 tickets split between the team’s preseason home games to Heads Up Football youth programs.

‘USA Football Month,’ a national campaign that takes place throughout the NFL preseason, incorporates youth football scrimmages at NFL stadiums and shares USA Football messages during network preseason telecasts. USA Football developed the Heads Up Football program to address the complex challenges of player health and safety in youth and high school football. Details can be found online at usafootball.com.

While the NFL safety policy remains unchanged, this year fans entering at the Shopko Gate will become the first to use newly installed walk-through metal detectors. A league-wide mandate for use at all stadium gates for 2016, the units will be phased in at Lambeau Field with the Shopko Gate debut this season and at all remaining gates next season. Unlike the screening machines at airports, guests are asked to not remove any jackets, belts, coins, keys, wallets, watches, or other objects of similar size. Guests will instead be asked only to remove cell phones, cameras, tablets and other large metal objects and place these items in an extended tray alongside each machine in close proximity and in clear sight.

As in previous years, no bags or purses will be allowed inside Lambeau Field unless they are clear plastic, vinyl or PVC and are no larger than 12” by 6” by 12”. Small clutches that do not exceed 4.5” by 6.5” are permitted. Stadium cushions are also not allowed, however, stadium seats and stadium pads that contain no pockets or zippers and are 18” wide or smaller are allowed.
