The Falcons have ruled rookie LB De'Vondre Campbell out for Sunday's game at Oakland because of an ankle injury he suffered in practice Thursday. That will leave Sean Weatherspoon starting in place of the guy who led all Falcons LBs in snaps played last week. Weatherspoon carries some low-end IDP appeal. Campbell's absence also might help Raiders TE Clive Walford a bit. Atlanta views Campbell as key to their TE coverage.
