The Buffalo Bills host the Kansas City Chiefs on Sunday in what’s easily the most highly-anticipated matchup of Week 11. Bills quarterback Josh Allen is in the midst of an MVP-level season thus far.

In 10 games, Allen’s thrown for 2,281 yards and 17 touchdowns along with 261 rushing yards and four scores.

While Chiefs quarterback Patrick Mahomes isn’t having his best statistical season, Kansas City travels to Highmark Stadium with a perfect 9-0 record. In fact, the Chiefs haven’t lost a game since Christmas Day last year. ”

Anytime you’re going against a quarterback like Pat you’ve got to make sure that on the offensive side of the ball you’re doing everything right,” Allen told reporters.

“That’s all we’re trying to do, is just have a good week of practice and then just go try to go out there and execute against a really good defense on Sunday.”

While the 28-year-old quarterback is locked for the AFC showdown, his little sister, Makenna Allen, attended Taylor Swift’s Eras concert in Toronto.

Considering Swift is famously dating Chiefs tight end Travis Kelce, the timing of Makenna’s attendance immediately turned some heads.

While she will likely rock a No. 17 jersey at Highmark Stadium on Sunday, during Night 2 of the Eras show at the Rogers Center in Toronto, Makenna is a Swiftie. She wore a silver sequin mini dress with sparkling blue cowboy boots.

Makenna appeared to have incredible seats close to the stage and posted a brief three-word message on her experience at the sold-out concert.

While fans can expect to see Makenna and numerous members of Allen’s family at the Bills-Chiefs game, CBS reported that Swift was also “expected” to attend.

After Saturday’s Eras show, the “Blank Space’ singer has four days off before kicking off another three-night run at the Rogers Centre. Swift has attended five Chiefs games so far this season, however, all of them have taken place at Arrowhead Stadium.
