Jacobs (groin) isn't practicing Friday, Matt Schneidman of The Athletic reports.
It's the second straight day that Jacobs is being held out of practice due to a groin injury. At this point, there doesn't seem to be any concern that the veteran running back is dealing with a serious issue, but Green Bay doesn't figure to rush him back onto the field at this early stage of the preseason. Chris Brooks (hamstring) also isn't practicing, so Marshawn Lloyd should get plenty of first-team reps.
