The Vikings just finished their morning walkthrough and coach Mike Zimmer chatted with us for more than 18 minutes afterward before grabbing lunch and preparing for this afternoon's practice. He covered a lot of ground, including ground covered yesterday, but there were some newsy nuggets.

For starters, the Vikings made some roster moves. They waived veteran wide receiver Josh Cooper, who had joined the team in June, and undrafted rookie tackle Matt Hall. Replacing them on the 90-man roster are second-year wide receivers Ty Walker and Andy Cruse. Walker has spent time with the Packers and Seahawks and Cruse was previously with the Texans.

The Vikings also placed three players on the physically-unable-to-perform (PUP) list. Cornerback Captain Munnerlyn is the headliner. He is dealing with a hamstring injury, and while Zimmer indicated that it isn't serious -- "I doubt it will be very long," he said -- those injuries can be tricky for cornerbacks. Also on the PUP list are safety Andrew Sendejo (lower back and ankle) and tight end Chase Ford (foot). Those three cannot do anything on the practice field until they are cleared by doctors and removed from the list.

Zimmer said that only one player failed yesterday's conditioning test and hinted that that man won't be allowed to practice, but he wouldn't say who. We'll try to get an answer for you this afternoon.

As for the decision on whether to bring in an external interim special teams coach while special teams coordinator Mike Priefer is suspended, Zimmer said he hasn't made it yet and that he will let us know soon. And then we will let you know ASAP. Priefer is allowed to coach during camp and this morning was doing his usual thing with assistant Ryan Ficken at the end of the walkthrough.

A couple of Zimmer quotes stood out to me on the 18-plus minutes of audio tape.

The first was on Adam Thielen, the former Minnesota State Mankato standout who is obviously still a popular guy down here in Mankato. Zimmer said he has improved tremendously.

"Adam's actually doing a terrific job," Zimmer said. "He might have been our most improved guy in OTAs. He's a great kid, first of all. Works his read end off. Runs routes real hard. Catches the ball good. He's got an opportunity to make this football team."

The second was Zimmer talking about how training camp will be different now that he has to worry about coaching and evaluating a whole 90-man roster, not just the defensive guys.

"I like to evaluate the players. The only difficult thing for me as opposed to being the defensive coordinator, I was evaluating 45 guys, I guess it was. Now I'm evaluating 90. I have to pay a little bit more attention to certain positions -- the left guard or the center or the right guard. You see the tackles all the time because you're watching them going against the [defensive ends]. Receivers, I see all the time. So it's just more volume, I guess, for me, trying to get that done. But I've got a list of things on my board that I'm going to make sure I do every single day, [and one of those things] is trying to evaluate all the players, trying to figure out how they can help us win football games and what their role can be. I try to remind myself every day to do that."

Oh, and Zimmer said it wasn't him who pulled the fire alarm at Sears Hall around 1:30 a.m. this morning, sending shirtless Vikings scurring out of the building. "Now that I think about it, I wish it was," he said. "I'll have to use that next year."

OK, I'm going to finish my burrito now. More to come in a little bit. Practice starts at 3 p.m.
