The Dallas Cowboys may be America's darling NFL team, but the San Francisco 49ers just manhandled them in front of national TV during Week 5 of the new season.

The Cowboys bowed to the 49ers, 10-42, in a game dominated by coach Kyle Shanahan's squad.

Dak Prescott is aware that they got no chance in the game and did not mince his words in describing the defeat, which, according to him, was the worst in his career.

"Didn't see it coming," Prescott told reporters after the match.

"Put everything into it and got punched in the mouth. Called it a couple weeks ago humbling against Arizona, but this may be the most humbling I've ever been a part of. Felt good about the preparation and felt good about everything, honestly, coming into this game, matchups, and they beat us in every aspect."

Coach McCarthy felt they were bullied

Coach Mike McCarthy' has a similar sentiment with his star. He said his boys have been feeling good about themselves - being prepared and all - but things turned out differently in front of the 49ers.

"It's a punch in the gut, it's a kick in the ass, whatever phrase you want to put on it," McCarthy said.

"We've been knocked down, clearly. They beat us in all three phases. We will clearly acknowledge it. I've never been a burn-the-tape guy. I think that is a crock of s---. We're going to go through it, make sure we're clear on exactly what the expectations are and make sure we're giving the players what they need to be successful."

The Cowboys fell to 3-2, and redemption time will be in Los Angeles when they face the Chargers for Week 6.
