The NFL sent a memo to teams, warning them against “faking injuries” to slow down up-tempo offenses, but, on Sunday night, that’s just what Dallas Cowboys owner Jerry Jones thought the New York Giants were trying to do.

As the Cowboys were trying to speed things up, Dan Connor went down because of a burner and Cullen Jenkins hurt his shoulder on successive plays.

“I thought us experts on football were the only ones who could see that,” Jones told ESPN’s Todd Archer, who added that Jones laughed and winked — perhaps because the Cowboys had won 36-31. “No, it was so obvious it was funny. It wasn’t humorous because we really wanted the advantage and knew we could get it if we could get the ball snapped.”

There was plenty of booing in JerryWorld, but no penalty flags. In last week’s memo, the NFL warned teams that there could be discipline even if no flags were thrown.

Connor did not return to the game, but Jenkins did moments later.

This isn’t the first time Jones has flashed some sass at the Giants since the NFL imposed that salary-cap penalty on the Cowboys and the Washington Redskins. Last year, he kicked off training camp with a little trash talk.
