Dak Prescott Fined $25K For Praising Fans For Throwing Trash At Refs

Dak Prescott's foot-in-mouth moment following the Cowboys' loss on Sunday just cost him serious cash ... 'cause the NFL announced Thursday it's fining the Dallas QB $25K after he praised fans for throwing trash at refs.

Following a controversial end to the Cowboys vs. 49ers game at AT&T Stadium ... fans hurled garbage at officials as they exited the field of play.

One bottle actually hit Cowboys star pass rusher Demarcus Lawrence ... and when Dak was informed that the debris-throwing was actually aimed at umps, he commended the acts.

"S***," Prescott said. "Credit to them, then."

Dak was immediately panned for the comments -- and the criticism grew so loud, he eventually apologized.

"I deeply regret the comments I made regarding the officials after the game on Sunday," the 28-year-old said. "I was caught up in the emotion of a disappointing loss and my words were uncalled for and unfair."

He continued, "The safety of everyone who attends a game or participates on the field of a sporting event is a very serious matter."

"That was a mistake on my behalf, and I am sorry."
