The controversy stems from a play in the fourth quarter of the AFC Championship, as the Jaguars led, 20-10. After a trick play, Patriots running back Dion Lewis was stripped of the ball by Jaguars linebacker Myles Jack.

Nearly eight months after the Patriots stormed back from a fourth quarter deficit to defeat the Jaguars, 24-20, in the AFC Championship game , one particular play still stands out in the minds of some Jacksonville fans. And it could result in a flyover banner prior Sunday’s game against New England.

Officials blew the play dead after Jack’s recovery and spotted the ball at the point of the recovery.


WOWWWWW.

The Jaguars offense went three-and-out on the ensuing possession, giving the ball back to Tom Brady and the Patriots, who marched downfield for a touchdown.

The controversy becomes popular

In the minds of some Jaguars fans (though not the NFL’s league office), the officials’ ruling was a pivotal turning point that unfairly cost their team. This was summed up in April from the fan behind the popular Twitter account @BortlesFacts.

“Myles Jack wasn’t down” became a rallying cry for Jaguars fans. Jack referenced it in his Instagram story in May, spotting a sign with the sentence at a professional wrestling event.

“I love it,” Jack told ESPN during the offseason. “I’m a B-list celebrity on this team. We got Blake [Bortles], Leonard [Fournette], Jalen [Ramsey]. Anywhere I can get my name in there, I’m cool with it.”

Clothing has been printed, and even a special beer was brewed. Intuition Ale Works in Jacksonville released a “Myles Jack Wasn’t Down Belgian Tripel” in June.

At a high school graduation in Jacksonville, Jack’s name-dropped at the end of a valedictorian’s speech.

The planned flyover for Week 2

Now in the 2018 season, Jaguars fans haven’t forgotten about the play or rallying cry. A Jaguars fan group, Generation Jaguar, began a GoFundMe campaign to raise money to pay for a flyover banner. The plane will drag a banner reading, predictably, “Myles Jack Wasn’t Down,” with a reference also to the fan group’s website.


There's a GoFundMe (started by @generationjag) to get a 'Myles Jack Wasn't Down' banner to fly during the Patriots game 🙌 #dtwd https://t.co/a570Z8aI3V pic.twitter.com/gqc1qMsCoF — The Teal Towel (@TheTealTowel) September 2, 2018

The group eclipsed their goal of $1,500, and promises to donate any additional money to Tom Coughlin’s Jay Fund Foundation. (Coughlin is a team executive).

“The only thing that would potentially stop our pilot from successfully flying the ‘MYLES JACK WASN’T DOWN’ banner on Sunday is inclement weather,” says Generation Jaguar on the GoFundMe page. Kickoff is scheduled for 4:25 p.m., and thunderstorms are in the forecast on Sunday afternoon.

But if the weather holds, the banner will fly.

“The banner will fly for at least 1 hour prior to kickoff, but the more we raise, the longer we can fly,” the GoFundMe page read.
