Uh oh.

Darrelle Revis, the Jets' All-Pro cornerback who is seeking a contract extension, did not show up for today's organized team activities.

Is it possible Revis' absence is related to anger over financial negotiations?

Rex Ryan, for one, didn't sound any alarm bells.

“We’ll see what happens,” Ryan said. “When it’s time to react or be frustrated and all that kind of stuff, I’ll react. With Darrelle, he’s been here every day up until this. He volunteered to be here every single day and now he wasn’t here today. These are voluntary camps just like there are voluntary workouts and he’s made every one of them until today. I’ve been impressed with him, to say the least, the way he’s worked.”

Ryan added: “I love him. He’s a great guy. The fact that he wasn’t out there today, this is voluntary camp. So you’d have to ask him the reason why he wasn’t here.”
