At least one arrest has been made amid the tailgating around Lincoln Financial Field, police said.
The arrest took place around 3 p.m. Sunday, more than three hours before the Eagles-Vikings NFC Championship game's scheduled 6:40 p.m. kickoff. Officers were called to the lot due to reports of a disturbance, a police spokesman said.
Police did not provide the name of the man taken into custody. Pictures on Twitter show officers on horseback apprehending him. He is shirtless with a bloodied face.
