"Matt worked again this morning in our walk-through," Smith said. "He continued to progress, and we're going to make a decision as we get closer to game time."
Pro Bowl running back Michael Turner, who missed last weekend's 34-7 home loss to the Philadelphia Eagles with an injured ankle, was limited in practice and is listed as questionable for Sunday's game. Four other offensive starters -- Pro Bowl wide receiver Roddy White (knee) left tackle Sam Baker (elbow), center Todd McClure (knee) and right guard Harvey Dahl (ankle) -- also are questionable.
NFL.com's Steve Wyche reported Wednesday that the availability of Dahl and Baker could be the final factor in the Falcons (6-6) determining if Ryan suits up against the Saints (12-0), according to a team source. The Falcons don't want to put a wounded, immobile Ryan under center with backups at key offensive line positions.
Babineaux was limited in practice, and Smith said he has yet to decide if the fifth-year veteran will be allowed to play against the Saints.
