The New York Jets, Indianapolis Colts, Tennessee Titans, Arizona Cardinals and Washington Football Team are among the NFL teams not practicing Thursday in response to the police shooting of Jacob Blake in Wisconsin.

The Green Bay Packers, Jacksonville Jaguars and Chicago Bears have postponed the start of their practices, with some using the time to instead meet as a team to discuss social change.

The Jets' practice field was set up for the usual start at 9:20 a.m. ET, and some staff members were seen walking the field -- but it was confirmed at 9:24 that practice was canceled.

Coach Adam Gase and a few Jets players said Wednesday that they spoke about the shooting of Blake and racial injustice on Tuesday night, and the virtual meeting included team chairman and CEO Christopher Johnson.

Instead of practicing, the Colts said they will use Thursday "to discuss and work toward making a lasting social impact and inspiring change in our communities."

Blake, a Black man, was shot seven times by police Sunday. Blake was shot as he attempted to enter the driver's side door of his vehicle with three of his children inside. Video of the shooting was distributed on social media, sparking more protests and causing more athletes to speak out or take action.

The Dallas Cowboys did practice Thursday, but coach Mike McCarthy said conversations with players will continue as to what they should do.

"I have to be honest, it's hard to sit here and to think I have to talk about football today, especially with everything that's going on in our country," said McCarthy, whose family lives in Green Bay, Wisconsin. "I've spent the evening, last night, listening and watching, everything that's going on in the NBA, the WNBA, the MLB and across our league. These are unprecedented times in our country. ...

"Spent a lot of time on the phone the last couple of evenings. It's definitely concerning. Having friends and family back there [in Wisconsin]. These times are unprecedented. Things need to change. I grew up in a home of public safety, but I mean, I just don't understand why it keeps happening and I think I'm like everyone else. I don't have the answers, but things need to change."

The New Orleans Saints are practicing Thursday, but cornerback Janoris Jenkins took to social media Wednesday night, posting a picture of a quote from Muhammad Ali next to his helmet, which had a strip reading "Jacob Blake" across the front.

Detroit Lions coach Matt Patricia said he and his staff check every day to see how players are feeling when it comes to practicing or not or discussion points that they potentially want to have.

"If there's any chance that maybe we got everybody to stop and think for a minute, that's really great," Patricia said of the being the first professional team to protest Tuesday by canceling practice. "And I think we have a simple saying, which is just listen. And right now, that's just what we want everyone to do, is listen. We understand that this is not a sprint. It's not a race. It's a marathon, and it's something that we just have to do a good job of continuing this conversation."

The Baltimore Ravens decided to practice but announced that they will "come together for a meeting to discuss and work on a plan for continued social justice reform efforts" after practice.

Atlanta Falcons coach Dan Quinn said he would talk with players, including the team's social justice committee, after Thursday's practice.

"We've always acted collectively as a group and as a team," Quinn said. He said he will support players "whether it's action items or a chance to vent as a team."

Washington made its decision to cancel practice Wednesday night after coach Ron Rivera talked to new team president Jason Wright, a former NFL player and the first African American team president in the NFL.

"In place of our practice at FedEx Field, the players, coaches and football staff will meet as a football family and we'll continue our open dialogue on the issues of racism and social injustice in out country," Rivera said in a statement.
