Back to work.

Travis Kelce arrived in Kansas City, Mo., for Chiefs training camp on Sunday — and he brought back his mustache.

According to a video shared online, the tight end smiled and greeted screaming fans as he walked into practice.

Kelce rocked a red Chiefs jersey that donned his jersey number, 87, on the front, red Nike shorts and a pair of red-and-white Jordan 1 cleats. He also carried his helmet and a pair of orange gloves in his hands.

“Thanks for coming out today, guys,” he told the fans as he walked into training camp.

Sunday marked the first day Kelce, 34, had to be back for practice with the rest of his teammates.

The team, which won the 2024 Super Bowl in February, will continue practicing every day until their season kicks off in August.

Four days ago, Kelce had traveled to Germany to support girlfriend Taylor Swift at her Eras Tour stop in Gelsenkirchen.

The NFL star, who was dressed casually in a black-and-green checkered polo shirt, white shorts and a baseball cap, was spotted enjoying the sold-out show from a VIP section of the venue, which featured a balcony and closed-off room.

After the concert, Kelce couldn’t keep his hands off the pop star, also 34, as they walked backstage.

The three-time Super Bowl champ wrapped his arm around Swift’s waist as they walked out and waved to concertgoers. The couple — who went public last September — also held hands in the Veltins-Arena and at one point, he had his hand on the “Bad Blood” singer’s backside.

While Kelce is back on the field, Swift will be continuing her Eras Tour abroad.

The “Cruel Summer” songstress will have several dates until Aug. 20 and then she will have a break until Nov. 14.

During that time, Swift is sure to catch a few of Kelce’s football games.

A source told People earlier this month that the billionaire musician is planning to attend “as many games as possible” this season during her busy schedule.

Swift’s tour wraps on Dec. 8 in Vancouver, Canada.
