The San Francisco 49ers started off the season looking like the top team in the NFC, but after a bad loss a few weeks ago to the Giants and a weird tie last week to the Rams, we're not so sure anymore. In tonight's "Monday Night Football" game against the Chicago Bears, they'll have a chance to show they are top contenders once again. However, they'll have to do it with backup QB Colin Kaepernick (Alex Smith is concussed), but their defense will also be facing a Bears backup QB (because Jay Cutler is concussed, too). All of these concussions might make for a sloppy game on the field, but on the sidelines it will be a different story. That's because the San Francisco 49ers cheerleaders, known as the Gold Rush, will be providing a sexy form of entertainment that Frank Gore and Vernon Davis can't. And in the spirit of Thanksgiving week, we're doing an extra long gallery of our weekly NFL cheerleaders, so here are 30 hot photos of the 49ers Gold Rush. Give thanks!
