Brooks (soreness) was working off to the side with a trainer during Wednesday's practice, Mike Kaye of ESPN.com reports.
Brooks has been dealing with some soreness in an undisclosed area for the past couple of days, as coach Dave Canales has been vague when describing the running back's issue. There doesn't seem to be any indication Brooks is in danger of missing Week 1 against the Bears in 11 days, but he's going to need to get back on the practice field next week.
