NEW YORK -- Liberty guard Brittany Boyd sat on the bench with her head bowed during the national anthem.
Hours earlier, college football players for Michigan and Michigan State, along with a group of students at North Carolina, raised their fists during the playing of the Star Spangled Banner on Saturday.
Since 49ers quarterback Colin Kaepernick refused to stand for the anthem before NFL preseason games, citing racial injustice and police brutality, his movement has slowly spread across fields and courts in the U.S. On Saturday, college athletes and professional athletes joined together to follow his lead after a week punctuated by riots in Charlotte, North Carolina , and the killing of an unarmed black man in Tulsa, Oklahoma .
Boyd had sat on the bench during the anthem at the team's last home game on Sept. 13, too. Her New York teammates stood, arms locked with their heads bowed before their WNBA playoff game with Phoenix. Mercury players Mistie Bass and Kelsey Bone kneeled, just as they had done during their first round playoff game. Bass was inspired that younger athletes were joining an effort that until this weekend, had been mostly led by the pros.
"I think it shows that the younger generations are about this and they did it together," she said. "They are understanding what is going on in our society. It's perfect because they are so caught up in their phones. To see them standing up for social injustices and wanting things to be right in their communities I think is awesome."
Three Michigan State players -- Delton Williams, Kenney Lyke and Gabe Sherrod -- held their right fists in the air while standing on the sideline before the No. 8 Spartans hosted No. 11 Wisconsin.
"Whether somebody salutes, puts the hand over their heart or does something else, everybody has a choice to make," Michigan State coach Mark Dantonio added after the Spartans' 30-6 loss. "Our young people are in college, and I can promise you one thing, that when the flag is presented in some respect, I guess it becomes much more important now. It's not just, oh by the way, we'll just stand for 'The Star-Spangled Banner.'
"All I can do is try and lead the best way I can, and be positive and accepting to our football team and our players," the coach added.
Several players for No. 4 Michigan also had their fists up before facing Penn State in Ann Arbor, Michigan. Among them were Khalid Hill, Mike McCray, Devin Bush, Elysee Mbem-Bosse and Jourdan Lewis.
Most college conferences play the anthem before the teams take the field. The Big Ten is among the exceptions.
The University of Michigan is 6 miles from Eastern Michigan University, where chanting students marched on the field Friday night after the school's 27-24 victory over Wyoming. The students were protesting racist graffiti on the campus earlier in the week.
"We have great respect for our students engaged in the constructive efforts underway to address the issues we face," Eastern Michigan President James Smith said in a statement Saturday.
Before North Carolina hosted Pittsburgh, students wearing black shirts remained seated with fists raised. Some 60 to 70 black and white students participated.
Michigan coach Jim Harbaugh was Kaepernick's coach for four seasons in San Francisco. Last month, Harbaugh said he supported Kaepernick's motivation to speak out but took exception to his method.
Saturday's gestures came a day after it was announced that Tommie Smith and John Carlos will join the U.S. Olympic team at the White House for a meeting with President Barack Obama. The raised-fist salutes by the American sprinters on the medal stand at the 1968 Olympics became a political flash point.
