Update: Fox News issued a statement Tuesday morning apologizing for using 'unrelated footage' of the Eagles in its coverage.

Philadelphia Eagles tight end Zach Ertz expressed anger on Twitter over a video Fox News posted Monday night that showed the Pro Bowl player kneeling to pray.

Fox News' video covered President Donald Trump's decision to cancel the Eagles' trip to the White House to celebrate their Super Bowl title. When Trump learned many of the team's players were expected to skip the event, he said he would not welcome a small delegation of Eagles.

In the video that drew Ertz's ire, Fox News pointed out Trump's criticisms of players who took took a knee during the national anthem to protest social injustice. But Ertz never took part in a national anthem demonstration, aside from a Week 3 game in which the entire team stood and locked arms during the playing of "The Star-Spangled Banner."

Ertz, a devout Christian, did pray before games, however. He reposted Fox News' video with this message: "Praying before games with my teammates, well before the anthem, is being used for your propaganda?! Just sad, I feel like you guys should have to be better than this..."

This can’t be serious.... Praying before games with my teammates, well before the anthem, is being used for your propaganda?! Just sad, I feel like you guys should have to be better than this... https://t.co/kYeyH2zXdK — Zach Ertz (@ZERTZ_86) June 5, 2018

No active member of the Eagles remained in the locker room during the national anthem in 2017 or knelt before a regular-season game. Cornerback Ron Brooks took a knee before a preseason game, but he didn't make the regular-season roster.

Safeties Malcolm Jenkins and Rodney McLeod raised their right fists in the air during the national anthem before every game in the first three months of the season to protest the oppression of people of color, they said. Defensive end Chris Long joined them by placing his arm around Jenkins as a show of support.

All three stopped protesting in December after the NFL pledged $89 million to social justice causes.
