The Associated Press reported that stadium staff extinguished the blaze as the National Anthem was sung.

Pyrotechnical equipment used for pregame festivities was to blame for the fire, which broke out near the 5-yard line, the AP reported.

A Titans spokesman did not immediately respond to a request for comment.
