Kamara (knee) was unable to finish Saturday's practice due to injury, Nick Wagoner of ESPN.com reports.
Kamara needed to be carted off the field due to the issue. The severity of the injury is unclear, but it seems the undrafted free agent out of Indiana has joined much of the 49ers' linebacker corps on the injury list. With the state of the corps, if any young players such as Kamara can recover quickly, they will have an inside track to climbing the depth chart.
