Links: Redskins to sit RGIII in preseason

Dallas Cowboys

Tony Romo is working with his sixth center -- Travis Frederick -- since he became the starting quarterback, but so far in camp the QB-center exchange has not been an issue, writes ESPNDallas.com's Todd Archer.

Day 4 of Cowboys training camp brought the most competitive part of a practice with two-minute and final-minute situations, writes Archer.

Cornerback Morris Claiborne dislocated his left pinkie during one-on-one drills, writes ESPNDallas.com's Calvin Watkins in an injury report following Wednesday's practice. Here's Watkins' Day 4 practice report.

Hamstring pulls are the most common injury at Cowboys training camp, writes Rainer Sabin of the Dallas Morning News.

New York Giants

The Giants come in at No. 12 on Frank Schwab's preseason power rankings.

When scouts watch Justin Tuck, they see "a player with diminishing skills, slower speed and a body that’s just been too beat up over eight NFL seasons," writes Ralph Vacchiano of the New York Daily News, and given what's at stake for the Giants and Tuck this season, they desperately need those scouts to be wrong.

Philadelphia Eagles

The Eagles will honor former quarterback Donovan McNabb at halftime of their Sept. 19 game against the Kansas City Chiefs. When asked by the Daily News' Paul Domowitch if he was concerned he might be booed by Philly fans, McNabb said, "I truly wouldn't care. To me, it's an appreciation for the people who truly respected what I did. I've always lived by the motto that you can't please everyone. So, for me, if I get booed, it wouldn't be anything new. If they cheer, that would be great. Obviously I'll be out there with my family and the teammates I played with. If there are any boos, I will smile."

Les Bowen of the Daily News has a practice report from the NovaCare Complex where the Eagles used the third day of camp as a teaching day.

The Eagles claimed former Arizona Cardinals running back William Powell on waivers. To make room on the roster, they released wide receiver Nick Miller.

Washington Redskins

The Redskins won't play Robert Griffin III during the preseason, and the quarterback is just fine with that, writes Mark Maske of the Washington Post. "I feel like I can play," Griffin said. "I think Coach [Mike Shanahan] feels like I can play without any preseason. So there’s no need really for that."

"We want to be a top-five, top-ten defense," nose tackle Barry Cofield said in a Q&A following Wednesday's training camp conditioning test. "We’re not in the business of making excuses. It’s like we’ve got some new toys with the guys that we’ve brought back from injury. A guy like [Brian] Orakpo, a [Brandon] Meriweather, guys like that, that we expected to really help us last year who are just hungry and starving to get out on the field and help us this year, so it’s extremely exciting and we expect to improve in every aspect."

The Redskins were never serious contenders to sign free agent offensive tackle Eric Winston, who signed with the Arizona Cardinals on Wednesday, writes Maske.
