Saints starting cornerbacks Marshon Lattimore and Ken Crawley have been ruled out of Sunday's game against the Rams, according to NFL.com.

New Orleans has been surprisingly stingy on defense this season, especially through the air, where they rank ninth in the league allowing just 211.3 yards per game.

Lattimore, the 11th overall pick in this year's NFL Draft, exited last week's win over the Redskins early with an ankle injury. He has been one of the best cover-corners in the league this year, racking up 36 tackles, nine passes deflected and two interceptions.
