The NFL has placed a temporary ban on "all flame effects and pyrotechnics used on its playing fields" following an on-field mishap at Nissan Stadium ahead of Week 2's Tennessee Titans-Indianapolis Colts game, according to ESPN's Kevin Seifert and Turron Davenport.
The ban will last until the league completes its investigation into the matter.
Last Sunday, one of the pyrotechnic machines used for player introductions in the corner of the field malfunctioned, resulting in flames being shot horizontally instead of vertically:

FIRE ON THE FIELD: Intense flames and smoke erupted at Nissan Stadium when one of the pyrotechnics machines used during player introductions caught fire ahead of the Tennessee Titans game against the Indianapolis Colts. Nobody was injured. https://t.co/3t4KNcRJof https://t.co/hKgXQmgkkT
The fire was eventually extinguished, and the machine was covered with sand. The incident did not result in any delay to the opening kickoff.
The Titans issued a statement following the game, via Juan Buitrago of the Nashville Tennesseean:
"Following the pregame introductions today, there was a mechanical failure by one of the pyrotechnic devices which resulted in a fire. The vendor will be required by the state of Tennessee to undergo an inspection for the defective device and the others that were used to determine the final cause. The field staff acted quickly to extinguish the fire, which resulted in no injuries and minor field damage."
Caitlyn Shelton of Fox 17 Nashville reported Thursday that a state fire marshal and a Nashville fire marshal are further looking into the matter.
According to a statement from the Minnesota Vikings, via Seifert and Davenport, teams will still be permitted to use pyrotechnics that are away from the field in the meantime.
