The sideline in Chicago on Sept. 24 is empty, because the Pittsburgh Steelers decided to not come out to the field during the anthem, although one Steeler player stood outside the locker room in the tunnel before the start of the game against the Bears. NFL player protests increase after Trump's attacks More players kneel, lock arms or just stay in the locker room.

President Donald Trump’s swipes at the NFL and at protests by players sparked a wave of demonstrations before football games on Sunday as athletes and coaches across the league kneeled, linked arms or declined to take the field during the national anthem.

"I think it’s very disrespectful to our country," Trump said Sunday afternoon in Morristown, New Jersey. "I think it’s very, very disrespectful to our flag."


The president's weekend tweets and statements related to the world of sports were met with strong pushback from athletes and owners alike, even from supporters such as New England Patriots owner Robert Kraft. "I am deeply disappointed by the tone of the comments made by the President on Friday," he said in a statement Sunday.

In Sunday's first NFL game, which was played at Wembley Stadium in London, multiple players on both the Baltimore Ravens and Jacksonville Jaguars kneeled during the anthem. (The players stood as "God Save the Queen" was played.) Jaguars owner Shahid Khan, a backer of Trump during the 2016 campaign, locked arms with his players.

On Sunday afternoon, the Pittsburgh Steelers opted to remain in the locker room during the anthem, with one exception: Alejandro Villanueva, a West Point graduate and veteran of combat in Afghanistan. He stood near the end of the tunnel, however, leaving the Steelers sideline virtually empty in the moments before their game in Chicago. Coach Mike Tomlin told CBS it was a team decision to avoid having his players side against one another.

Later in the afternoon, both the Tennessee Titans and Seattle Seahawks stayed in their locker rooms before their game in Nashville, leaving the field largely empty in the minutes before kickoff. "We will not stand for the injustice that has plagued people of color in this country," Seattle's players said in a statement that also affirmed their commitment to working "towards equality and justice for all."

Players in other games also stood up by kneeling down or sitting on the bench; others locked arms with their teammates. In Detroit, artist Rico Lavelle went down to one knee while singing the anthem; singer Meghan Linsey later did the same in Nashville.

"Collectively we felt like we had to do something," said Denver Broncos linebacker Von Miller in summing up the reaction of many players.

Trump tweeted in response to the players' actions Sunday afternoon: "Great solidarity for our National Anthem and for our Country. Standing with locked arms is good, kneeling is not acceptable. Bad ratings!"

In his series of tweets, Trump was referring to players such as former San Francisco 49ers quarterback Colin Kaepernick, who has not been signed to a team this year after he drew attention for his political activism, as well as such outspoken players as Malcolm Jenkins of the Philadelphia Eagles and Michael Bennett of the Seahawks.

Some of these players have declined over the past year to stand for the national anthem as a form of protest against racism in American society, including police tactics seen as targeting African-Americans. Others have made different gestures, such as raising their fists.

But the president rejected the notion that his position was racially inflammatory. The NFL, according to reports in recent seasons, is approximately 70 percent African-American. "This has nothing to do with race. I never said anything about race," Trump said Sunday afternoon in New Jersey.

After remarks on the subject Friday during a campaign rally for Alabama Sen. Luther Strange, the president has spent the weekend seemingly at war with professional sports.

Trump attacked the commissioner of the NFL ("Roger Goodell of NFL just put out a statement trying to justify the total disrespect certain players show to our country.Tell them to stand!") and the defending NBA champion Golden State Warriors ("Going to the White House is considered a great honor for a championship team. Stephen Curry is hesitating,therefore invitation is withdrawn!")

A day after disinviting the Warriors, the president on Sunday noted the Pittsburgh Penguins, champions of the National Hockey League, would be visiting the White House. However, the University of North Carolina said its NCAA championship men's basketball team would not go to the White House.

Trump began Sunday with yet another criticism of the football league, tweeting that "if NFL fans refuse to go to games until players stop disrespecting our Flag & Country, you will see change take place fast. Fire or suspend!" The president then added: "NFL attendance and ratings are WAY DOWN. Boring games yes, but many stay away because they love our country. League should back U.S."

"He thinks this is about respect for the military," Treasury Secretary Steven Mnuchin said Sunday about Trump on CNN's "State of the Union," "and so many people who put their lives at risk and what the country stands for."

Iowa Rep. Steve King backed Trump. "Pro-Players have the right to freedom of speech. Owners do, too. And should exercise it by firing offending players," the Republican lawmaker tweeted.

But former Sen. Rick Santorum, who has been working to get the latest Obamacare repeal bill passed, said Trump's energies could be better spent on trying to get that bill through the Senate. "He is taking his eye off the ball," the Pennsylvania Republican said on "State of the Union."

Trump's stand drew a sharp counter-reaction throughout the sports world.

Goodell, the son of a former U.S. senator, pushed back Saturday: “Divisive comments like these demonstrate an unfortunate lack of respect for the NFL, our great game and all of our players, and a failure to understand the overwhelming force for good our clubs and players represent in our communities.”

On Sunday, Goodell got a backanded compliment from former Pennsylvania Gov. Ed Rendell, a part-time sports analyst. He tweeted: "Only Donald Trump is dumb enough to make Roger Goodell look smart!"

Cleveland Cavaliers star LeBron James on Saturday called Trump a "bum" ("Going to White House was a great honor until you showed up!") and Buffalo Bills star running back LeSean McCoy called Trump an "asshole" on Twitter. Oakland A's catcher Bruce Maxwell kneeled during the "The Star-Spangled Banner" in Saturday's baseball game. "I'm kneeling for the people who don't have a voice," said Maxwell, the first MLB player to make the gesture.

Former Buffalo Bills head coach Rex Ryan, who campaigned for Trump, said he was "pissed off" by the president's comments. "I'm reading these comments and it's appalling to me and I'm sure it's appalling to almost any other citizen in this country, it should be," said Ryan, now an analyst on ESPN's Sunday NFL Countdown.

A number of NFL team owners also pushed back against the president, noting the role that sports plays in American society.

"Every day I see the genuine dedication and hard work of our players," said Eagles owner Jeffrey Lurie on Saturday. "And I support them as they take their courage, character, and commitment into our communities to make them better or to call attention to injustice. Having spoken with our players, I can attest to the great respect they have for our national anthem and all it represents."

Lurie stood with Jenkins and defensive end Brandon Graham on the sideline Sunday before his team's game in Philadelphia against the New York Giants.

Kraft, CEO of the NFL's New England Patriots and an early supporter of Trump during the 2016 campaign, expressed his disappointment with Trump on Sunday.

"I am proud to be associated with so many players who make such tremendous contributions in positively impacting our communities," he said in a statement Sunday. "Their efforts, both on and off the field, help bring people together and make our community stronger. There is no greater unifier in this country than sports, and unfortunately, nothing more divisive than politics."
