Sprint Cup champion Kyle Busch shows off Denver Broncos pride

While the majority of the NASCAR world was wrapped up in Sunday's NFL playoffs game between the Carolina Panthers and the Seattle Seahawks, current Sprint Cup champion Kyle Busch was more concerned with the fate of the Denver Broncos.

The Joe Gibbs Racing driver has been a longtime fan of the team, and is apparently sharing that love with his young son, Brexton.

That a boy!! Go Orange! RT @brextonbusch: Congrats @Panthers now let's go @Broncos !! 🍼🏈

Luckily for the Busch family, Peyton Manning and the Broncos were victorious over the Pittsburgh Steelers 23-16.

Busch was not the only one in the NASCAR community pulling for the Broncos, either.

Regan Smith, whose 2016 racing plans are still up in the air, is also a Broncos fan and was relieved to see the victory formation at the end of the game. Cole Pearn, crew chief for Martin Truex Jr. and the Denver, Colorado-based Furniture Row Racing team, also had his eye on the game and cheered for the local team.

Nervous is an understatement right now... Let's go @Broncos!!!!

Next weekend, the Broncos will face the New England Patriots for the AFC Championship to determine which team heads to the Super Bowl.
