Around the NFC West: Singletary and more

Posted by ESPN.com's Mike Sando

Matt Maiocco of the Santa Rosa Press-Democrat says NFL rules would prevent the 49ers from removing the "interim" label during the season. The 49ers would hold exclusive negotiating writes for an unspecified period of time. I see no advantage in making a hasty decision.

Also from Maiocco: The 49ers signed rookie free agent Carl Stewart, a running back, to their practice squad after losing defensive lineman Attiyah Ellison to the Jaguars.

Matt Barrows of the Sacramento Bee says the short term prognosis for Frank Gore might not be good. The 49ers aren't sure if their running back will be able to play on a bad ankle.

Frank Hughes of the Tacoma News Tribune says Leroy Hill has a chance to play against the Rams, a departure from previous reports suggesting Hill wasn't recovering quickly. Also, Holmgren singled out Floyd Womack for having the best game of his career against the Patriots. Holmgren also thought Steve Vallos played well despite a late miscue. Finally, Maurice Morris will start at running back once again.

Also from Hughes: Patrick Kerney has again torn the labrum in his left shoulder. This is a huge setback for Kerney.

Dave Mahler of KJR Radio in Seattle interviews Seahawks receiver Nate Burleson, who says he's ahead of schedule in returning from knee surgery. Office warning: This is an audio file, which is why the link is way down here.

Clare Farnsworth of the Seattle Post-Intelligencer says the Seahawks have signed center Donovan Railoa to their practice squad after losing guard Pat Murray to the Broncos.

Danny O'Neil of the Seattle Times says Seahawks quarterback Matt Hasselbeck will be questionable against the Rams.

Kent Somers of the Arizona Republic says the Cardinals have signed linebacker Kelly Poppinga to their practice squad after losing linebacker Chris Harrington to the Bengals.

Darren Urban of azcardinals.com has the latest on Alan Branch. An infected cheek kept the 2007 second-round choice from buckling his chinstrap, preventing Branch from practicing.

Mike Tulumello of the East Valley Tribune thinks the Cardinals would have been a Super Bowl contender had they drafted Adrian Peterson instead of Levi Brown.

Note: Nothing from the Rams so far.
