GLENDALE, Ariz. (AP) -- St. Louis cornerback Marcus Roberson is inactive with an ankle injury for the Rams' game Sunday against the Arizona Cardinals.
The rookie was injured in last weekend's win over St. Louis and did not practice all week. However, the Rams did get starting cornerback Janoris Jenkins back for the Cardinals game. He had been listed as questionable with a knee injury that had kept him out of the previous two games.
St. Louis middle linebacker Daren Bates also was inactive with a groin injury. He had been listed as doubtful.
Arizona was without running back Stepfan Taylor, who already had been declared out for the game with a calf injury.
Defensive lineman Ed Stinson was active. He injured a groin last week in practice and was questionable for the game.
