Schalke and U.S. midfielder Weston McKennie published a video on social media on Wednesday that mixed footage of police officers using force against black people with clips of football players and other athletes saying: "Enough is enough."

Chelsea and U.S. midfielder Christian Pulisic took part in the video, as did Bayern Munich and Canada left-back Alphonso Davies and women's World Cup winner Mallory Pugh of the U.S.

Former U.S. international Clint Dempsey and DaMarcus Beasley, as well as current national team players Jozy Altidore and Michael Bradley also took part in the video.

Several players in Germany have made statements with gestures during games or messages on their clothing since George Floyd died on May 25 after a white Minneapolis police officer pressed his knee for several minutes on his neck.

​McKennie begins the segment by saying: "This has been going on for way to long. To the cops out there that continue to abuse their power, the world is watching now. Enough is enough."

ENOUGH IS ENOUGH ✊?✊?

The time is NOW!! Not just for justice or change, but a SOLUTION!!! It has been going on way too long. This has been overlooked and belittled way too often! ENOUGH IS ENOUGH!!! pic.twitter.com/IqM18XjTga

The German soccer federation, said earlier on Wednesday it opposed punishing any players for on-field protests related to Floyd's death because it believes their anti-racism messages match the federation's own principles.

"The DFB has made a strong stand against any form of racism, discrimination or violence and stands for tolerance, openness and diversity, values which are also anchored in the DFB's statutes," federation president Fritz Keller said in a statement. "Therefore the players' actions have our respect and our understanding."

The statement named four players who protested during last weekend's games -- Dortmund's Achraf Hakimi, Jadon Sancho, McKennie and Borrussia Monchengladbach's Marcus Thuram -- but made clear the same approach would apply to any future protests.

The federation has not revoked a yellow card given to Sancho for removing his jersey after scoring a goal. The federation said on Monday that the Borussia Dortmund forward's booking was for the act of removing his shirt, rather than for the "Justice for George Floyd" message written on his undershirt during Sunday's 6-1 win over Paderborn.

Other players protested by kneeling, like Thuram, or by showing messages on an armband, like McKennie, or on boots, like Leipzig midfielder Tyler Adams. Only Sancho received a booking.

There were also social media statements, such as one from United States national team goalkeeper Zack Steffen, who is on loan at Fortuna Dusseldorf but isn't playing because of injury.

"Demonstrating against racism and police brutality is not political act. It's about human rights that should be a given," tweeted Steffen, who also took part in McKennie's "Enough is Enough" video.

Germany's approach has the backing of FIFA. The governing body of world footbal said on Tuesday that such demonstrations "deserve an applause and not a punishment."

Hungary has taken a different approach. Their league gave a written reprimand to a player of African origin, Tokmac Nguen, who displayed a message in solidarity with Floyd after scoring a goal for Ferencvaros on Sunday.

UEFA, the governing body of European football, is also set to allow messages related to Floyd and anti-racism when the Champions League resumes.

Players are normally prohibited from espousing their views during a match. The laws of the game state that "any political, religious or personal slogans, statements or images" on equipment is forbidden.
