A video diary on the team's official website showed Mathieu cutting and back-pedaling, leading Cardinals assistant athletic trainer Chad Cook to say that the playmaking defender is "real close to getting back to football."
Coach Bruce Arians said last month that he didn't expect Mathieu back on the field until the team's Week 5 matchup against the Broncos, but the safety is hoping to put on a helmet and shoulder pads for individual drills at training camp. Honey Badger acknowledged that his elongated and lonely rehab has been frustrating.
"It's like when you are in elementary school and you wait all day for recess," Mathieu said. "But you had been bad that morning and then teacher says you can't play with the rest of the kids."
