The start of the St. Louis Rams game against the Pittsburgh Steelers was delayed nearly 30 minutes by a small fire from sparks emitted during a pyrotechnic display for player introductions.
The cleanup effort appeared to be hampered by a malfunctioning wet-dry vacuum used to remove fire extinguisher foam.
There was a small circular mark between the 3 and 4-yard line near the north end zone as the game began.
It appeared the fire started as the rest of the Rams players trotted through towers that shot flames high into the air.
At one point, both teams left the field.
