Bruce Arians was much happier about Tuesday's practice than he had been about Monday. "I knew they'd bounce back," he said, and it was all but necessary with a game coming Thursday. For the first time in camp, Arians split the team to two fields, in order to ramp up the reps for the younger players that will be playing against the Cowboys.

Many vets, actually, will not play. Arians ruled out the starters (although we'll see if that ends up being all of them; do you consider giving Evan Boehm a few reps at right guard, for instance?) as well as backup quarterback Drew Stanton and new cornerback Tramon Williams. Stanton doesn't need more reps with four preseason games left, and Williams still needs to learn the playbook.

While things were better Tuesday, they weren't perfect. At the end in particular, Arians said "some young guys" had trouble getting lined up correctly in a two-minute drill. There were a couple of guys who could've gotten out of bounds after catches who didn't, and Arians ended practice upset on the last one.

"Run a  great route, fall down and catch it, don't get up and get out of bounds," Arians said. "There's only nine seconds left those are things you hopefully learn from. Everyone else should learn from them also."

The last two days have been about learning from B.A. "If you can't learn it after I get after you, you're in trouble anyway."

-- Injuries bit cornerback, and now they are biting inside linebacker. Karlos Dansby (knee) wasn't going to play Thursday anyway, but he's missed three straight practices. Arians isn't concerned. But backup Gabe Martin is out for a while with an Achilles injury, and newcomer Phillip Wheeler is day-to-day with some unknown aliment. Arians would rather not play Haason Reddick a lot Thursday. Scooby Wright and Zaviar Gooden are in line to get a lot of playing time Thursday.

-- On the good side, cornerback Justin Bethel returned -- Arians Monday had said it'd be another week, but then again, Williams showed up -- and Arians said "it was great to see him today. He was full speed." Outside linebacker Jarvis Jones is also doing more and more at practice.

-- It's been clear Tyrann Mathieu has been playing well as he rounds into Honey Badger shape, but he had a couple more interceptions during drills Tuesday. A high-level Mathieu is always fun to watch.

-- Veteran kicker Phil Dawson was kicking at narrow practice goalposts at the outset of practice. No, there was no snap or rush. But Dawson nailed 60- and 63-yard field goals within the thin opening. It was impressive.
