McCarthy pleased with toughest day of camp

Green Bay Packers coach Mike McCarthy spoke to the media after Wednesday's practice. Here are some highlights of the news conference:

On interceptions:

We've gotten our hands on a few balls. You get around the quarterback off the spot. Good to see secondary bringing it.

On playing time in Saturday's preseason opener at Tennessee:

My goal for playing time is you want all your young guys to play. We want to make sure all our young guys get a chance to show what they can do.

On whether he'll hold back any starters from Saturday's game:

I haven't gone that far yet. Get through today and we'll get play times out Saturday before practice.

On disguising plays in preseason:

Most people don't show what they're going to show against Seattle. We are an open-practice football team compared to most of the league. We have been practicing inside and doing some things. We won't show what we're doing in the first four weeks of preseason.

On skipping the last three periods of Wednesday's practice:

The fundamentals are optional. This was our toughest practice of training camp. I'm excited to look at the work.

On Wednesday's warm-weather practice:

You definitely want some heated days. This was clearly the hottest day. It's good for us. Tennessee Saturday night will be a challenge.

On whether rookie wide receiver Jeff Janis will play Saturday:

Janis, we put him on a schedule no different than football team. Today was his first padded work. We'll see how he feels tomorrow.

On defensive tackle Letroy Guion's status (out with a hamstring injury):

Guion, I really don't have a feel.

On safety Morgan Burnett's status (out with a strained oblique):

I was told day-to-day on Morgan Burnett. I'll see how he is doing tomorrow.

On tackle Derek Sherrod's growth and tackle Don Barclay's status:

I'd say Derek Sherrod is stronger now than when he came in. Don Barclay has a torn ACL.
