It was a special moment for Carson Steele's family to watch his first start with the Chiefs

Most Kansas City Chiefs fans are probably watching Week 3 Football on Sunday evening They can watch the game against the Atlanta Falcons from the comfort of their own home – but not Carson Steele’s family.

The Chiefs running back made his first NFL appearance on Sunday night, and his family watched Steele in action at his sister's wedding reception. In a video shared by Carson's older sister Kessler, the Steele family could be seen watching the undrafted rookie take his first snaps as a starter on a giant TV screen at a wedding reception.

What a special moment.

Carson's sister reportedly sent out a save-the-date invitation over a year ago, and Carson was set to be best man at her wedding. The Chiefs running back was obviously needed elsewhere, however, as Kansas City looked to score its third win of the season and a coveted third straight at Mercedes-Benz Stadium on Sunday.

The 6-foot-4, 220-pound Steele joined the Chiefs as an undrafted rookie last offseason. Steele played two college seasons at Ball State, where he rushed for over 1,500 yards and 14 touchdowns in his sophomore year, before transferring to UCLA.

Steele rose in the running back rankings after Isiah Pacheco was placed on the injured list, although he is still expected to share some snaps with pass-catching back Samaje Perine.
