Chiefs Fan Buried Special Flag Underneath Super Bowl Stadium in Las Vegas in 2017

Football fandom makes people do some wild things.

The Kansas City Chiefs may already have some good mojo working when they step into Allegiant Stadium for Super Bowl LVIII on Feb. 11 to take on the San Francisco 49ers—thanks to a loyal fan who worked on the stadium’s construction.

When the Las Vegas venue was being built in 2017, construction worker Gerard DeCosta buried a Chiefs flag under the field, the Las Vegas Review-Journal reported.

By burying the flag, DeCosta presumably was trolling the Las Vegas Raiders, one of the Chiefs’ AFC West rivals. But now the prank may be perceived as good luck when the Chiefs return to the stadium for the Big Game.

It’s unknown whether the flag is still buried under Allegiant Stadium as Raiders fans have claimed they dug up the flag.

DeCosta’s trolling didn’t end with just the flag prank, though. In 2018, he posted a picture of himself sitting on the stadium’s brand new grandstands wearing Chiefs gear, via KMBC-TV in Kansas City. He claimed to be the first fan to sit in the Allegiant Stadium seats.

So far, the Chiefs have won every game they’ve played in Allegiant Stadium, posting a 4–0 record against the Raiders.

Super Bowl LVIII between the Chiefs and 49ers kicks off at 6:30 p.m. ET on Feb. 11.
