Not a lot can be said about Tuesday's practice, other than it was outside, because it was closed -- which means that, like the regular season, everything there is under wraps and cannot be reported upon. But the Cards did get outdoors in the heat, going through a short walkthrough period before having about an hour of regular work. That allows coach Kliff Kingsbury to give his players a taste of non-building practice without grinding them up.

"It's a change of scenery, change of the schedule a little bit, getting used to the heat and the sun," Kingsbury said. "I thought they bounced around pretty good."

The Cardinals do play the majority of their games inside. The heat probably won't be much of a factor (although that second week in Baltimore may or may not be toasty.) Then again, once camp breaks for good, the team will be practicing at least some of the time outside back in Tempe at the Dignity Health Arizona Cardinals Training Center.

-- Kingsbury said quarterback Kyler Murray was "up and down" in practice Tuesday. "He's a perfectionist like a lot of those guys," Murray said. "But it's good. It's a humbling game. It's not always going to go your way."

-- Offensive linemen A.Q. Shipley and J.R. Sweezy had days off. Shipley has been solid in camp and seems headed toward winning the starting center job.

-- The Cardinals still have two practices left in camp -- one open to the public -- after the Raiders game, then they return to Tempe.
