W2W4: Cowboys training camp: Day 16

By Calvin Watkins

OXNARD, Calif. -- The Cowboys are nearing the end of training camp and are in preparations for their third preseason game of the summer at Arizona.

Here's a preview:

Injuries piling up: Cornerback Morris Claiborne (knee) is the latest Cowboys player out, and it appears he won't practice this week. There are a few other players, including Eric Frampton (hamstring), Alex Albright (back), Ernie Sims (groin), Sean Lissemore (knee) and J.J. Wilcox (personal), who most likely won't play against the Arizona Cardinals. With the bulk of the injuries on defense, it leaves the unit short-handed.

More zone read: The Cowboys worked on defending the zone read offense in Monday's practice. The Cowboys will face two teams -- Philadelphia and Washington -- who use a form of it, and the Oakland Raiders ran a few plays in the second preseason game against them. Dwayne Harris was the quarterback for the zone read and coach Jason Garrett said his team has to prepare for it for when they see it during the season.

Waters update: There's nothing really to report Tuesday morning regarding Brian Waters. The Cowboys have made an offer to Waters, but he's still thinking about it. The Cowboys are trying to bolster the interior of the offensive line because of injuries to Ryan Cook, Kevin Kowalski and Nate Livings and the unknown with Ronald Leary, who hasn't played in a NFL regular season game. The Cowboys want a veteran presence as a swing guard in case of more injuries.

Armstrong moving up: If the Cowboys keep six receivers, Anthony Armstrong has the lead for a spot. His special teams play will help in the discussion as to whether to keep him, but he's doing a nice job with his route running and catching tough passes. Jared Green is still in the mix, but his two drops against the Raiders in the fourth quarter didn't help his cause.
