Cardinals' Tyrann Mathieu: Expected to be 'full speed' for Week 1

Head coach Bruce Arians expects Mathieu (knee) to be "full speed" for the Cardinals' season opener on Sept. 11 against the Patriots, Darren Urban of the team's official site reports.

Analysis:

According to Arians, Mathieu doesn't require game action in order to suit up in Week 1. Instead, the All-Pro defensive back needs "8-to-9 days of practice," which should be plausible with nearly two weeks until the showdown with the Pats.
