When Macklemore was kicked off Ed Sheeran's tour, he alleged that Robert Kraft and other NFL owners presented the “Shape of You” singer with an “ultimatum.”

In short, if Macklemore remained on the tour, the venues wouldn't allow him to perform. Furthermore, Sheeran wouldn't be allowed to perform either.

Now, some of the NFL owners who co-signed the “ultimatum” have emerged, per the Wall Street Journal (via TMZ). Carolina Panthers owner David Tepper, Atlanta Falcons owner Arthur Blank, and Philadelphia Eagles owner Jeffrey Lurie allegedly backed Kraft.

Bear in mind, Sheeran's next scheduled show on the Loop Tour was at Lincoln Financial Field on Saturday, Sep. 19. The Eagles lease the stadium from the city of Philadelphia. Similarly, the Falcons' stadium is operated by Blank but owned by the state of Georgia. The Panthers' stadium received public funding. Meanwhile, Kraft owns the Patriots' Gillette Stadium.

The drama began after Macklemore went on a political rant that featured a “Free Palestine” chant during his opening set during Sheeran's concert at MetLife Stadium on Sep. 4. He delivered a similar speech the following night.

As a result, he was let go from Sheeran's tour. Macklemore alleged that Sheeran was given an “ultimatum,” ultimately choosing to let him go and move on with the tour.

This caused an avalanche of others dropping out from the tour. Beoga, his backing band who recorded songs like “Galway Girl” and “Nancy Mulligan” with Sheeran, dropped out, as did some of his other opening acts, Lukas Graham, Finneas, and Aaron Rowe.

The Loop Tour has 10 dates remaining on its only North American leg. It resumes on Sep. 19, and as of the time of this writing, Sheeran is without an opening act.

Macklemore has since donated $1 million to six groups assisting Palestinians. He challenged Kraft to match his donation. The Patriots owner then donated $2 million to aid Palestinians amid the war in Gaza. Sheeran was reportedly behind the decision to double the donation.
