What was Dalvin Cook drinking on sideline before Cowboys debut?

Dallas Cowboys Nation was thrilled when Dalvin Cook was elevated from the practice squad for the team's Week 8 showdown against the San Francisco 49ers.

Unfortunately, when it came to his primetime performance, it was a complete nothingburger.

Cook had just 12 yards on six carries. For those doing the math at home, he averaged only two yards per carry. His biggest play was a 10 yard receptions, which was his only catch of the game.

The highlight of Cook's performance actually came before the game when cameras captured him drinking an unknown substance.

Social media immediately began cracking jokes about Cook taking the edge off with a shot of liquor.
