"He's going to be out there playing with his hair on fire," Fitzgerald said, "like he always does."
Mathieu is a little more cautious.
"Just from a morale standpoint, losing him last year was a kick in the stomach," receiver Larry Fitzgerald said. "You see a guy who's battled back from injury the year before and to see it happen again, it was demoralizing for all of us. You feel sorry for him but you also feel sorry for your team because he was such a big part of it."
Now he wants to resume the role that made him such an important part of the team.

He will wear a brace, but a much smaller one than he did after his first surgery.
"If I'm out there I'm going to make some plays," he said. "I just want to be prepared mentally. Physically I'm all right. We'll see how it goes."
