Here's a message directly from the team:
"The Giants encourage fans to arrive early and be patient about entering the stadium on Monday night. The enhanced security procedures at the stadium gates recommended by the NFL will increase the comfort and safety of fans at the game, but will require some additional time for inspections at the gates. Fans are asked to come early, enjoy the best tailgating tradition in the NFL, and take advantage of the video boards and other new amenities outside MetLife Stadium.
"In addition, fans are urged to arrive at the stadium early because players from the 1986 Super Bowl XXI championship team, which will be honored at halftime, will be throughout the stadium plaza making appearances and signing autographs.
"In order to accommodate this security enhancement, guests are asked to arrive earlier than normal to avoid longer security lines at the checkpoints. Guests may refuse inspections; however, stadium management reserves the right to refuse entry."
