Travis Kelce is staying focused on the Kansas City Chiefs’ quest for back-to-back Super Bowl wins.

With the NFL star’s girlfriend, Taylor Swift, nominated for six awards at this weekend’s upcoming Grammy Awards, Kelce, 34, has confirmed he won’t be able to attend the annual show, which takes place on Sunday, Feb. 4 in downtown Los Angeles.

On Wednesday, Kelce appeared on The Pat McAfee Show, where he said, “I wish I could go support Taylor at the Grammys, and watch her win every single award that she’s nominated for.”

Then, Kelce slyly added, “But I think I’ve got practice on Sunday.”

The Chiefs tight end wasn’t certain if his team would use Saturday as a practice day and Sunday as a travel day, but Kelce explained that his schedule just won’t allow for him to attend the show while staying focused on Kansas City’s fourth Super Bowl in five years.

“Unfortunately, I’ve gotta get ready for this big old Super Bowl that we’ve got in a week,” Kelce added on the show.

Fans speculated the possibility that Kelce would attend the Grammys with Swift, 34, after the “Lover” singer supported him at Sunday’s AFC Championship win in Baltimore and with the awards show happening the weekend before the Super Bowl.

Swift and Kelce did get to publicly support each other on Sunday, and their on-field celebration set the internet ablaze as they shared several kisses and the NFL star was heard saying, “I love you.”

A source close to the couple told PEOPLE that Sunday’s victory celebration was “the best night ever” for Swift and the Kelce family. “Having his family there, all his best friends and managers, and of course, Taylor, celebrating with him was very special.”

The source said that Kelce “was feeling every single emotion” on Sunday. “The whole family was so, so excited and riding a high. Their phones were blowing up all night with congrats. The energy on the field was just insane.”

“Now he and the team are focusing on the Super Bowl,” the insider added.

According to the insider, “It’s going to be an intense couple of weeks,” as the Chiefs prepare for the big game. But as Kelce gets through the grueling practices, he’ll have Taylor on his side.

“It’s obvious, isn’t it? They’re genuinely happy together,” the source continues. “She’s there to support him and cheer him on, and she’s fit in seamlessly with everyone he loves.”
