The Raiders on Saturday placed S Jeff Heath on IR with his concussion. That knocks him out for at least Week 14 through Week 16, meaning you should drop Heath from all IDP rosters. Erik Harris looks like a good bet to start the rest of the way. He doesn't land high in our Week 14 IDP rankings but is an option.
Cowboys S Jeff Heath (shoulders) is inactive for today's game against the Lions. That should mean a start for Darian Thompson, who played 87% of the snaps after Heath left last week and totaled 5 tackles (2 solo). Thompson is merely a low-level IDP in a spot that hasn't meant big points for Heath this year.
