Speaking of Kelce, his girlfriend, Taylor Swift, is at Arrowhead for Sunday's game and she had a nice message while getting off a golf cart inside the stadium. Security guards could be heard yelling "stay back" at people. The pop star then could be heard saying, "stay back, please."

Denver previously announced the team’s jersey color for all 17 games earlier this year, but players pick the color of their pants each week. The Broncos’ home games this fall will feature jersey colors white (once), blue (once), throwback (twice) and orange (four times).

Swift arrived at Sunday's game shortly before kickoff at 1 p.m. ET. The singer wore a matching red and black plaid blazer and skirt, paired with a black corset and all black accessories. She was photographed at Arrowhead Stadium arriving in a golf cart alongside her mom, Andrea.
