Taylor Swift would have had a short drive from Toronto to Buffalo for Sunday’s game between the Kansas City Chiefs and Buffalo Bills, but the pop star reportedly decided to remain north of the border.

Swift is wrapping up her Eras Tour with a series of shows in Toronto, but had a break of several days that lined up with Sunday’s game. That led to speculation that she would be in attendance at Highmark Stadium outside of Buffalo, but reporter Dan Fetes, sports anchor for WHAM in Rochester, N.Y., noted before the game that Swift would not be in the stadium.

Indeed, the Bills beat the Chiefs and Swift’s boyfriend, star tight end Travis Kelce, 30-21, without Swift on hand.

While there was no confirmation as to why Swift skipped the game, Cosmopolitan’s Mehera Bonner reported it was a combination of issues that kept the singer from the game.

“There was some speculation that Taylor might attend since she doesn’t have an Eras Tour performance lined up today and was just in nearby Toronto,” Bonner reported. “But a few things to note: 1) Taylor is reportedly only attending Chiefs home games in Kansas City due to security reasons. And on top of that, sports commentator Adam Lefkoe says she and the Kelce family didn’t have the best time at last year’s Chiefs vs. Bills game in Buffalo.”

There had already been hints that Swift may not be attending many games away from Kansas City. A source told the New York Post’s Page Six in October that the singer was being careful about her security on the road.

“If she is going to a place that isn’t Arrowhead, there are security concerns,” the source said. “She has worked with Arrowhead so many times, they feel at ease and comfortable. Going to all kinds of different stadiums, you need to send a team in advance.”

Swift had a major security scare over the summer, being forced to cancel shows in Vienna after authorities said they thwarted a planned attack.

Swift’s first visit to Buffalo drew some viral attention, thanks in part to the antics of her boyfriend’s brother. Attending the game with Swift and his family shortly after his final game in the NFL, Jason Kelce spent time tailgating with Bills fans and jumped from their private suite into the crowd shirtless to drink a beer with fans.

The Chiefs have three remaining home games on the schedule. They will play the Raiders on Nov. 29, the day after Thanksgiving, and smack in the middle of a break in Canadian leg of the Eras Tour. She could attend that game, but the Chiefs play at home on Dec. 8 against the Chargers, and Swift will be playing in Vancouver that evening–the Eras finale.

Their final home game will be played on Saturday, Dec. 21, against Houston.
