Red-White practice details:

When: The practice is scheduled from 2 to 4:30 p.m. at University of Phoenix Stadium.

Parking: Fans can park on the east side (Green and Grey) and west side (Orange) of the stadium beginning at 12:30 p.m. Fans can enter University of Phoenix Stadium at Hyundai Gate 1 (west side) and through Bud Light Gate 3 (east side) at 1:30 p.m.

What to expect: The Cardinals are careful not to call Saturday’s Red & White practice a scrimmage, but there likely will be more full-team competition than on a normal day.

There will be short-yardage and goal-line sessions, as well as what Arians called a “move-the-ball scrimmage. Not sure who is tackling who yet but there will be a live scrimmage that we have not had in the past.”

The move-the-ball scrimmage usually features Arians calling the offensive plays and James Bettcher calling the defense.

The sessions are not scripted, which creates more of a game-type atmosphere.

An autograph session featuring the whole team will follow the practice.

Camping out

Camp confidential: The need for help at cornerback was highlighted on Friday when starter Justin Bethel missed practice. There was no update on why Bethel just watched. The choice of his replacement was interesting. It was not Brandon Williams, who was expected to compete with Bethel for the starting job. Ronald Zamort took Bethel’s spot on the first team. Zamort, a rookie free agent last year, was cut at the end of camp a year ago and signed to the practice squad in December. Williams was a third-round pick a year ago. The Cardinals have taken a look at veteran free-agent corners this week, and a roster move could be coming.

– Quarterback Carson Palmer wore pads to Friday’s practice but didn’t throw a pass. Drew Stanton, Blaine Gabbert and Trevor Knight took all the snaps.

– Wide receiver John Brown was having an impressive camp until suffering a quadriceps strain on Thursday. He’s expected to miss at least two days and as much as a week. Coach Bruce Arians said the strain was not related to Brown carrying the sickle-cell trait. Brown was hampered by fatigue and soreness for much of last season.

– Arians encourages his assistants to refrain from drawing conclusions about players based on their performances in non-padded practices. Many players play better once the pads go on. The Cardinals have had four such practices, and Arians said several players have performed better than they did in offseason workouts. Among the players Arians mentioned: rookie guard Dorian Johnson, linebacker Scooby Wright, safety Ironhead Gallon, safety Budda Baker, receiver Krishawn Hogan and defensive tackle Xavier Williams.

– Right tackle Jared Veldheer took Thursday’s practice off. Arians called it a “personal day.” Veldheer was back on Friday.

Friday’s Injury report: The Cardinals had two receivers go down in Thursday’s practice. In addition to Brown, WR Aaron Dobson (hamstring) will miss more than a week, Arians said. … Gallon (knee) was limited on Friday. OLB Jarvis Jones (quad), DT Ed Stinson (knee) are day to day. The Cardinals are hoping Gallon, Jones and Stinson can play against the Cowboys in the preseason game next week.

Quote: “He’s not flying under my radar. He might be under the national radar or all the people who say they don’t have a defensive line. But Josh has been as good a player as we’ve had for three years on the defensive line, as consistent. When he’s in the game, I don’t look his way because his job is getting done.” – Coach Bruce Arians on defensive tackle Josh Mauro.
