BBAO: Live chat with John Sullivan today

We're Black and Blue All Over:

MANKATO, Minn. -- I've got a cool treat to celebrate our third and final day at Minnesota Vikings training camp. In between the morning and afternoon practices, at around 12:45 p.m. ET, Vikings center John Sullivan will host a live chat right here on the NFC North blog with any of you that care to join us.

Sullivan, a Pro Bowl alternate last season, has returned to the field after offseason microfracture surgery on his knee. He'll be available to answer your questions on himself, the team, the state of the NFL or any other topic you might have for him.

The chat module will post at around 11 a.m. ET, and I would encourage you to submit your questions ahead of time. I'll also send out a few reminders on Twitter. Let's have some fun with it!

While we have a moment, let's round up weekend coverage here in the NFC North:

  • Vikings tailback Adrian Peterson still doesn't agree with the team's decision to trade receiver Percy Harvin. Peterson, via Dan Wiederer of the Star Tribune: "A: To me, this is how I look at it. I don't care what’s going on. I am not trading Percy Harvin. If anything, if he's going to hold out, it's this: 'You're going to sit right here and you're just not going to play. I'm not going to trade you.' That's me. That's me. So I was upset. This is a guy that you've seen what he's got. Best player I've played with. His athletic ability as a whole -- fast, quick, elusive, strong as an ox. And it's all compact in a little body. To me, he was a good guy. We all have our different ways, our personalities. And sometimes they don't click with certain individuals. … But to me, his was a situation that went overboard and it didn't really have to go there."
