The fan came on the field from the corner of one end zone Sunday and dashed across the turf for about 80 yards before tripping and then being jumped on by several security officers, including two New Jersey State troopers.
The man, wearing a maroon sweater, was handcuffed and led away from the field.
While the man was running, Jets coach Rex Ryan was shown laughing on the stadium's videoboards.
On the next play, Santonio Holmes scored on a 41-yard touchdown catch to give the Jets a 20-7 lead with 4:38 left in the third quarter.
The Jets eventually won 30-27 after scoring with only 10 seconds left in the game.
