Jones made the announcement following the team's 35-31 loss to the Green Bay Packers Sunday, saying the National Football League can not tolerate its players disrespecting the flag by kneeling or linking arms as popularized by Colin Kaepernick. "Understand? We will not. if we are disrespecting the flag, then we will not play".
"If it comes between the impression or the perception that we're not standing together, supporting each other, or the perception that we're disrespecting the flag, the perception that we're not together will be secondary to not respecting the flag", Jones said.

"I know this. He's been very pleased".
In the two games since, the Cowboys have stood during the national anthem.
"Trump has made [standing for the anthem] about patriotism", Ross said, on a day when three Miami players stayed in the tunnel rather than stand on the sideline during the anthem. Then, they locked arms and stood while Jordin Sparks sang the national anthem. "It's so important, if that's what the country is looking at, to look at it differently. They don't think it's disrespecting the flag".
