Fewer demonstrations.

The San Francisco 49ers played on Thursday last week, before President Donald Trump lashed out at NFL players for not standing during the national anthem.

So as teams across the league kneeled, sat and raised fists in protest, the team once at the epicenter of anthem protests was home watching it on TV.

With a week to think about it, the 49ers came up with their own demonstration of unity.

Just before Sunday’s game against the Arizona Cardinals, San Francisco’s players formed two lines for the national anthem. The players in the front kneeled and the players in the back remained standing, setting off a round of boos at University of Phoenix Stadium.

Many of the standing players placed one hand on their heart, the other on the shoulder of a kneeling teammate in a sign of solidarity.

“For more than a year, members of our team have protested the oppression and social injustices still present in our society,” the 49ers said in a statement. “While some may not have taken a knee or raised a fist, we have all shared the desire to influence positive change. Today, our team chose to publicly display our unity in a new way and, in turn, urge others do the same. Our demonstration is simply a representation of how we hope our country can also come together by putting differences aside and solving its problems.”

More than 200 players kneeled or sat during the anthem last Sunday after Trump criticized the NFL in a speech and a series of tweets .

A week later, the protests had diminished, even after the president tweeted about the anthem the day before.

“Very important that NFL players STAND tomorrow, and always, for the playing of our National Anthem. Respect our Flag and our Country!” President Trump said.

Most players in the early games Sunday stood for the national anthem, with a few exceptions.

Minnesota rookie star injured: The Minnesota Vikings might have lost their standout rookie running back for the season.

Dalvin Cook left in the third quarter with an injury to his left knee, and coach Mike Zimmer said the team is concerned about his ACL. Cook will have an MRI test to determine the extent of the damage. The second-round draft pick from Florida State had his knee buckle under him after planting his leg on the turf and trying to make a cut.

Cook fumbled on the play, and the Lions went the other way for the goahead touchdown in a 14-7 victory.

Latavius Murray took over at running back for the Vikings. Cook was second in the NFL in rushing entering the week.

Mariota gets hurt: Tennessee quarterback Marcus Mariota left the game against the Houston Texans with a hamstring injury.

It was unclear when he was injured, but he was replaced by Matt Cassel for Tennessee’s first possession of the second half.

Titans coach Mike Mularkey said he’ll know more about Mariota’s injury after he has an MRI on Monday.
