Jonathan Cooper ARI 2 Hrs

Cooper continues to be sidelined by a nagging bout with turf toe, the Cardinals' official site reports. "It's getting better each day, but it hasn't gotten to the point where I feel I can be effective and really evaluated fairly," he said.

Because Cooper occasionally breaks technique and plays on his toes, the injury is particularly bothersome. As a result, he'll yield left guard to Ted Larsen on Sunday against the Bengals. Consider Cooper day-to-day, but if his absence continues unabated, Larsen could hold onto the gig for good.

Tyrann Mathieu DB ARI 3 Hrs

Mathieu (knee) took part in 11-on-11 sessions at Thursday's practice, Kent Somers of the Arizona Republic reports.

Although he didn't initially make any hits, Mathieu eventually took down Ted Ginn following a catch-and-run, according to Darren Urban of the Cardinals' official site. Mathieu made his first appearance at practice Wednesday since suffering torn knee ligaments in December, after which coach Bruce Arians said that the organization would explore 11-on-11 work in a few days. Thus, Thursday's development is a surprising step for Mathieu and feeds the belief that he may suit up Week 1 versus the Chargers.

Jason Verrett DB SD 3 Hrs

Verrett (shoulder) is expected to log his first NFL action during Sunday's preseason contest at San Francisco, Michael Gehlken of the San Diego Union-Tribune reports.

The Chargers' first-round pick of the 2014 NFL Draft didn't make an appearance during the first two exhibitions due to his recovery from a torn labrum, but Verrett will factor into the defensive backfield Sunday. A significant number of snaps may be difficult to tear away from the cornerback duo of Brandon Flowers and Shareece Wright in his rookie season. Nonetheless, return duties haven't been promised to any Charger to date, a facet of the game in which the speedy Verrett could make an impact.

D. J. Williams TE NE 3 Hrs

Williams has been released by the Patriots, the Boston Herald reports.

Williams, who was a candidate to work as a depth TE behind Rob Gronkowski and Michael Hoomanawanui, hasn't practiced since suffering a right leg injury Aug. 5 and is thought to be about a week and a half away from practicing. Once he is healthy, the report suggests that Williams could be a candidate to re-join the Patriots.

Preston Brown LB BUF 3 Hrs

While he doesn't have a starting spot, Brown, a third-round rookie out of Louisville, continues to make quite the impression in camp, BuffaloBills.com reports.

Brown might actually get to start the first week of the season, as starting OLB Nigel Bradham is suspended for one game, and Brown seems to be leading the list of potential candidates for the temporary starting nod. Keep an eye on him this season, as he's following a similar path to what Kiko Alonso did in 2013.

Isaiah Pead RB STL 3 Hrs

After clearing waivers Thursday, Pead was placed on IR by the Rams, foxsports.com reports.

It's a predictable outcome for Pead after the 2012 second-rounder tore his ACL during Saturday's preseason contest against the Packers. Assuming no issues in his recovery, Pead will presumably have a shot to make a push for a spot in the team's backfield mix next year.

Eric Berry DB KC 3 Hrs

Berry (heel) did not practice Thursday, ESPN.com reports.

With Berry still ailing and unlikely to play Saturday against the Vikings, the Chiefs bolstered their depth at safety on Thursday, by acquiring Kelcie McCray in trade with the Bucs.

De'Anthony Thomas RB KC 4 Hrs

Thomas (hamstring) returned to practice Thursday, ESPN.com reports.

As did Jamaal Charles, with Thomas a name to file away in deeper formats, assuming -- as expected -- that he moves into the sort of versatile role in the Chiefs' offense previously held by Dexter McCluster.

Joe Mays LB KC 4 Hrs

Mays is expected to ungergo wrist surgery within the next 24 hours, ESPN.com reports.

Mays, who was viewed as the leading candidate to start at inside linebacker for the Chiefs opposite Derrick Johnson, is thus out indefinitely and off the IDP radar for the time being.

Derek Carr QB OAK 4 Hrs

Carr (concussion/ribs) won't play Friday against the Packers, according to NFL Network's Steve Wyche.

On the plus side, coach Dennis Allen relays that Carr has cleared his concussion protocol, but the rookie QB is still dealing with sore ribs at this stage and will be held out Friday.
