He was kicked in the calf in the game against Arizona and some swelling and pain came overnight. He went to the hospital and underwent a relatively minor procedure to drain the area. There will be no long-term problems, but he won't be ready to play against the Cowboys.
Taylor didn't have a sack against the Cardinals but he tipped a couple of passes to create some key incompletions.
I would think that Demetric Evans will start and play on running downs and Erasmus James will come in for passing situations.
Taylor is the second defensive starter to miss a game after being kicked in the leg. Shawn Springs missed the opener against the Giants after he was kicked in the shin during practice a few days before the game.
