Cornerback Kevin Dockery, who gave up a number of big pass plays last week, was among the Rams' inactives Sunday. Bradley Fletcher regained his starting spot after Dockery started the previous three games.
Abraham had been questionable. He is among the league leaders with eight sacks and had two in the Falcons' last game, a victory over the Ravens on Nov. 11.
Linebacker Sean Weatherspoon was active after being questionable because of a knee injury.
