Where was Dockett? Usually on sideline

News broke Thursday that Darnell Dockett would be available to the Arizona Cardinals in Week 5.

Cardinals DL vs. Rams

Arizona's game against St. Louis began, and Dockett was on the field. But as the game progressed and the Rams moved closer to a 17-3 victory in the Edward Jones Dome, Dockett didn't appear to be making an impact. Most of the time, I couldn't even find him on the field.

The reason: Dockett played only about one-third of the Cardinals' defensive snaps. He was available, but he wasn't right. The hamstring injury that forced him to miss the Cardinals' Week 4 game was still a factor.

Arizona now has nine days between games. Dockett will presumably be closer to full strength when the team faces Buffalo in Week 6.

Hamstring injuries can linger, however. Dockett, one of the most durable Cardinals, had been a dominant force for Arizona at times during the team's fast start. The chart shows playing time stats for the Cardinals' defensive line, as tabulated by the NFL.
