Colin Kaepernick reiterated his desire and readiness to play in the NFL in a conversation with Kenny Stills.
Stills has been continuing to protest while Kaepernick and Eric Reid have remained unsigned.
"I said, 'What are you doing?' He said, 'Just came from a workout. I'm ready to go,'" Stills said after Thursday's practice. "He wants to play. He's good enough to play. He deserves to play. I'm not sure why a team hasn't signed him yet."
Stills said earlier this offseason that a good first step for the NFL to show its contrition would be to "admit what it is doing" to Kaepernick and Reid, then allow them back in the NFL.
Reid signed with the Panthers on Thursday.
"I'm happy that Eric is going to be playing. He's a game-changer on the defensive side of the ball," Stills told ESPN. "I'm excited to see him play. I definitely think he should have been signed a long time ago. As far as what it means, it means a team was finally able to look past the protest. I think we're making some progress as far as how the owners, teams and GMs are understanding what the protest is about.
"That's progress, but we still have one of the best quarterbacks in the league sitting at home waiting to be signed. That'll be the ultimate say of how people look back on the NFL at this point in time. You got one of the best guys not playing on a team and there are teams out there that need quarterbacks."
