A proposed second meeting between NFL owners and the Players Coalition, tentatively scheduled for Monday, has been tabled.

The sides couldn't work out the details and are discussing trying again next week, sources told ESPN's Dan Graziano and Jim Trotter.

The meeting had tentatively been scheduled to take place Monday in Washington, D.C. But Saturday, on the heels of Houston Texans owner Bob McNair's controversial "inmates running the prison" comment, a coalition of NFL players invited McNair, commissioner Roger Goodell and quarterback Colin Kaepernick to a meeting Monday in Philadelphia. They said they hoped to address players' "immediate concerns before additional progress can be made."

49ers safety Eric Reid offered some insight on Kaepernick's attending the second meeting.

"I talked to him [Kaepernick]. I think if they could make it a legitimate meeting, then he'll go. But right now, we don't know if anybody is going," he said Sunday.

Reid went on to say that Kaepernick has struggled to get on the same page as the NFL.

"I know Colin has been fighting to get in the room to speak with the corporate people from the NFL, and thus far he hasn't been able to. We're just going to keep working on getting him in the room. He told me that he was explicitly told that he had no place being there [in the last meeting]."

Reid was also defiant in his thinking that Kaepernick should be in the room.

"I think, to keep it frank, the NFL wants the protests to end. It's bad for their business, but I think it's ridiculous that they don't want Colin to be there, being as he is the first one to start protesting. If we have to force him into that room, that's what we'll do. But it has to be under the right circumstances. We have to set a meeting, and there has to be people that are going to be there. I don't think he's going to fly out here to Philadelphia if nobody is going to be at the meeting."

The coalition consists of 11 players, including Malcolm Jenkins and Anquan Boldin, who met with NFL team owners on Oct. 17 in New York to discuss, in part, player involvement in communities and with law enforcement. A league spokesman said earlier this week that Kaepernick was expected to be invited to the next meeting between NFL players and owners.

"Many players have been deeply troubled by the disturbing comments made by Texans' owner Bob McNair," the Players Coalition said in a statement. "It is ironic that such a quote would emerge in the midst of an ongoing struggle to highlight injustices suffered by people of color, including our nation's deeply flawed approach to criminal justice and inhumane treatment of imprisoned people."

Jenkins was asked Sunday if he is surprised that the league didn't accept the meeting, considering the volatility following McNair's comments.

"I think so. Players have in good faith tried to stay patient and diligent about working in a collaborative way, so we're trying to just move this along," he said.

"It's already a sensitive issue. A lot of different opinions. What I am proud of is the fact that the voice of the player has been pretty concise and consistent, even when you've had responses from the president [and] responses from different owners that have not been in the good spirit of solidarity. Players have remained pretty level-headed, and we will continue to do so. We're more concerned about getting actual work done and change and going about the right steps to do that. And so hopefully, the league will show some signs of taking us serious. ... Behind closed doors, they've talked about supporting us and wanting to get something done, but as far as action, we really haven't seen much yet.

"Players have been doing things on their own time for the last year-and-a-half. They [the league] want to get back to football, [and] we want to move past anthem demonstrations, but to do that, we need to be able to replace the platform that we have."

Jenkins was also asked whether McNair's comments have been a setback for players.

"It's not a setback for us. It's disappointing, and it's definitely something that I think is frustrating because as players, I felt like we've been very patient, we've been very fair when it comes to dealing with ownership and what we put out there. And to have owners like Jerry Jones and comments that Mr. McNair said come out, it doesn't seem like the same respect that we've been giving them. But we know that dialogue is really the fastest way to change, and so we're still committed to pushing for that."

McNair apologized for the comments Friday and again Saturday, saying: "I am truly sorry to the players for how this has impacted them and the perception that it has created of me, which could not be further from the truth."

On Saturday morning, he met with Texans players and expressed regret for the initial comment. One day earlier, Texans players considered a walkout from the team facility, and two players -- star wideout DeAndre Hopkins and backup running back D'Onta Foreman -- missed practice because of the comments, sources told ESPN.
