Massive Fire At Dolphins Game Destroys Several Cars, Authorities Investigating

A huge fire broke out in the parking lot at the Dolphins vs. Patriots game on Sunday -- destroying several cars -- and according to at least one witness, it all started after someone left a tailgating grill on.

A spokesperson for Miami-Dade Fire Rescue tells TMZ Sports ... firefighters were called to Hard Rock Stadium at around 1:28 PM after multiple people had seen flames pouring out of cars just outside of the venue.

Thankfully, according to the spokesperson, "firefighters immediately worked to contain and place the fire under control" and there were no reported injuries.

Video shot by multiple people at the arena showed the inferno was massive -- causing huge amounts of black smoke to pour into the stadium.

One witness says the owners of the cars had no idea their rides were destroyed until they returned to the parking lot. Another said the blaze appeared to start after someone had failed to properly extinguish their BBQ.

The MDFR spokesperson said the cause of the fire is still under investigation.

One of the car's owners, Scott Dellorfano, told NBC Miami that his Mercedes S63 -- plus $3k he had in the vehicle -- were destroyed in the fire.
