There is no new veteran cornerback yet. But who knows, maybe one will become inherently necessary sooner rather than later. Justin Bethel ended up sitting out practice Friday -- he had a brace on his left knee -- and interestingly, Ronald Zamort was the one in his place with the first unit and not Brandon Williams. Zamort actually had a decent camp a year ago, but he was cut and not brought back to the practice squad. (The Cardinals ended up bringing in a bigger defensive back, Trevon Hartfield, for the PS.) Zamort was re-signed to the practice squad later in the season after injuries. It'll be interesting to see how he does in preseason games, and how Williams does as well.

(Not sure how Bethel was hurt. Bruce Arians didn't mention anything at the lunch presser. Bethel did have a play Thursday when he and tight end Jermaine Gresham collided and seemed to bump knees/legs, but Bethel finished practice after getting up slowly.)

-- Carson Palmer was technically back at practice but he threw little. Very little. He didn't go in during any of the 11-on-11 work, and he didn't throw much before that either. (Again, as Arians said earlier in the day, given the early start, all this work is "bonus" time for Palmer. I wouldn't read too much into the inactivity.)

-- Tyrann Mathieu had another pick in a drill, grumpy at one point that he was flagged for a hold he didn't think he should have. Mathieu is trying to be more low-key, but he's playing better and better.

-- Practice ended with a pair of situational periods. The first started around the defense's 30 with 22 seconds left and the offense down 6. That ended up all offense: A David Johnson TD catch for the first unit, a Troy Niklas TD catch for the second unit, and a clutch fourth-and-10 TD catch down the seam by tight end Ifeanyi Momah for the third unit.

-- The other sequence started on the offense's end of the field needing about 15 yards for a long field goal try and 19 seconds left. First unit's possession ended with a interception by Antoine Bethea. The second ended with a Josh Mauro sack. The third unit succeeded, with a Carlton Agudosi catch setting up a 56-yard field goal by the ageless Phil Dawson.
