Saints running back Chris Ivory will be "a gametime decision" for Sunday's game at Baltimore.

Ivory was listed as questionable with a hamstring injury. Saints head coach Sean Payton said he will work out Ivory before Sunday's game, then makes a decision on his status. Questionable, according to the NFL, means a player has a 50/50 chance of playing.

Payton said tight end David Thomas will miss two weeks after arthroscopic surgery Tuesday on a torn lateral meniscus. Kickoff return man Courtney Roby will not play after suffering a head injury against the Rams. Payton said running back Pierre Thomas and wide receiver Robert Meachem will both get duty as kickoff returners.

The game features the Saints defense, ranked 6th in yards allowed, against the Ravens, 10th in yards allowed. Said Saints defensive coordinator Gregg Williams, "I told em, whoever plays the best defense wins."
