More than ever, the Saints are going to need a big rookie season out of first-round pick Sedrick Ellis.
Without Thomas, it appears Kendrick Clancy will start at nose tackle and Ellis at the three-technique tackle. But Ellis does have the ability to play the nose and Thomas' injury could prompt some changes on the line.
The Saints might not make a decision immediately on whether to end Thomas' season. He'll likely be out for at least two months. Keeping him active would take up a roster spot that the Saints don't want to sacrifice.
