Around the NFC West: MRI for Cards' Breaston

Posted by ESPN.com's Mike Sando

Kent Somers of the Arizona Republic says the Cardinals feel as though they are taking steps toward improvement on defense. Strong safety Adrian Wilson: "I thought we played well. We can take a lot of positives from this game defensively. I think we executed what we wanted to execute, which was not to give up big plays, not to give up big running plays and try to keep everything in front of us and get off on third down."

Matt Levin of the Arizona Republic says Cardinals receiver Steve Breaston will undergo an MRI exam on a stiff knee. Coach Ken Whisenhunt did not sound concerned.

Darren Urban of azcardinals.com says the Cardinals expect rookie running back Beanie Wells to return from an ankle injury in time to play in the next exhibition game. Also, Whisenhunt was generally pleased with the Cardinals' performance against the Steelers.

Matt Maiocco of the Santa Rosa Press-Democrat says 49ers coach Mike Singletary didn't see much from the quarterbacks Friday night. He also called the pass rush non-existent. On the injury front: "Fullback Zak Keasey sustained a fractured right forearm. Running back Thomas Clayton sustained a right knee injury and was carted off the field in obvious pain."

Also from Maiocco: running commentary from the first half of the 49ers' game against Denver.

Matt Barrows of the Sacramento Bee says injuries to the 49ers' running backs could mean more playing time for scoring machine Brit Miller.

Also from Barrows: some in-game notes.

Tim Kawakami of the San Jose Mercury News says 49ers quarterbacks Alex Smith and Shaun Hill looked OK -- particularly compared to Kyle Orton.

Daniel Brown of the San Jose Mercury News quotes 49ers president Jed York as saying the team will eventually sign first-round choice Michael Crabtree. Not that York was going to say the team likely never would sign Crabtree.

Also from Brown: Dre Bly was quite pleased to pick off a pass against his old team.

Andrew Davidson of Niners Nation provides a 49ers game overview. Was that Brit Miller or Leonard Weaver out there?

Jim Thomas of the St. Louis Post-Dispatch says the Rams were generally pleased by their performance against the Jets -- and ecstatic for rookie quarterback Keith Null. Marc Bulger even retrieved the ball Null threw for his first NFL touchdown pass. Bulger: "I said, 'Who cares if it's preseason? It's still your first touchdown pass in the NFL. It was a great throw. That pass looked like it was (thrown) by a 10-year vet." Sounds like a little camaraderie.

Also from Thomas: Samkon Gado and Antonio Pittman were far better than Kenneth Darby. All three are battling to be the second-team running back.

More from Thomas: positives and negatives from the Rams. Rookies Brooks Foster, Sean Walker and Null made big plays.

Turf Show Times' VanRam saw improvement from the Rams' linebackers.

Greg Johns of seattlepi.com says the Seahawks will let backup quarterback Seneca Wallace get some snaps behind the starting offensive line.
Danny O'Neil of the Seattle Times sizes up the competition for one or two spots at receiver on the Seahawks' roster. I would think the team would find a spot for Ben Obomanu.

Also from O'Neil: The Seahawks are unapologetic about adopting cut-blocking techniques even though defensive linemen despise them.

Eric D. Williams of the Tacoma News Tribune explains how the Seahawks identify the strong side, thereby determining where Aaron Curry lines up.

John Morgan of Field Gulls sizes up the Seahawks' offensive line heading into the team's exhibition opener at San Diego. Morgan: "The other matter is seeing the team's progress zone blocking. Everyone matters, but I will pay special attention to Rob Sims, because he never looked good pulling in Mike Holmgren's system, and Ray Willis, because he has potential to be an elite run-blocking right tackle. Overall, the line must move and slide and block as a unit."

Also from Morgan: a look at attempts to project Matt Hasselbeck's production in 2009.
