Daniel Brown of the San Jose Mercury News says the 49ers are on the lookout for Saints running back Reggie Bush. I think Bush would fit very well in a Mike Martz offense because he's one of the few running backs with the ability to line up as a true receiver. As for the Saints, they are banged up. The 49ers have a better-than-anticipated shot at winning this game, at least in my view.

Howard Ulman of the Associated Press spoke with former Seahawks and Rams linebacker Isaiah Kacyvenski for a story about concussions. Kacyvenski, a special-teams standout with a history of concussions, has agreed to donate his brain to science upon his passing.

Darren Urban of azcardinals.com sets the scene at Cardinals practice in Washington, D.C. The team is working to eliminate a recent run of special-teams penalties.

Kent Somers of the Arizona Republic quotes Kurt Warner as saying the decision to stay on the East Coast all week will pay benefits Friday through Sunday.

Matt Barrows of the Sacramento Bee has an interesting (to me) note about Ahmad Brooks getting work at the "Ted" linebacker spot in practice after the 49ers targeted him for the "Mike" spot behind Patrick Willis. Brooks' body type made me think of him as a "Ted" candidate when the 49ers signed him. 

Chrissy Mauck of 49ers.com says J.T. O'Sullivan and Vernon Davis stayed after 49ers practice to work on their timing after a couple of near-misses against Detroit.
