The Colorado-Colorado State college football rivalry is alive and well.

After the Buffaloes defeated the Rams, 28-9, on Saturday, Colorado quarterback Shedeur Sanders refused to shake the hand of his Colorado State counterpart Brayden Fowler-Nicolosi at the 50-yard line.

Instead, Sanders called Fowler-Nicolosi out for previous comments.

"You were talking s-t on Instagram," Sanders could be heard saying in a video of the exchange. "Talking on Instagram. We handled our business. You can't f-k with me."

Fowler-Nicolosi told Sanders to "keep talking" as he walked away.

Earlier in the week, Fowler-Nicolosi added fuel to the fire with his thoughts on how last year's game in Boulder unfolded.

"They came out with that attitude and thought it was going to be a cakewalk," he said of the 43-35 Colorado win in an interview. "They saw the reports that it was 27.5 points. They got a rude, rude awakening real quick. I think it goes to show the hype, the media train, all that only gets you so far.

"At the end of the day, you have to line up 11 guys against our 11 guys and we'll find out who wants it more. We'll see how far Instagram followers gets them."

Additionally, during Saturday's game, Fowler-Nicolosi gave the "too small" gesture toward Travis Hunter.

The Colorado cornerback and wide receiver went on to intercept Fowler-Nicolosi later in the game.

Colorado coach Deion Sanders also got involved, pointing out the "disrespect" from Colorado State during his postgame news conference.

"Wonderful game, personal game, heartfelt game, emotional game," he said. "They kind of make it like that. We just want to play some football. The disrespect was uncalled for throughout the week. A couple of their players took shots at the whole program and a few of our players so it is what it is. So we knew coming into the game that it'd be a bit personal, and it was."
