According to NFL.com via ESPN, the MRI of 49ers running back Brandon Jacobs came back OK, after showing no significant damage to his knee.

“An MRI on the left knee of San Francisco 49ers running back Brandon Jacobs showed “no major damage,” NFL.com reported Sunday,” wrote ESPN.com.

My guess is that Jacobs suffered some sort of ligament sprain and will be out the rest of the preseason.  We’ll have to wait and see what the 49ers tell us.
