Cardinals' Tyrann Mathieu: Availability for Week 1 up in air

Mathieu's (knee) availability in Week 1 against the Patriots will be dependent upon his health, the Arizona Republic reports. "If I'm 90 percent, then I don't necessarily want to go out there," he said Sunday. "But if I'm 100 percent, I definitely want to be out there."

Analysis:

Embedded within his second rehab effort from a torn ACL -- the other occurred near the end of his rookie year in 2013 -- Mathieu's reticence to take the field isn't a shock, especially after logging just 13 games in a generally subpar 2014 season. With an unimpeded offseason under his belt last fall, he was the centerpiece of the Cardinals' defense, accumulating 89 tackles (80 solo), five interceptions (one for a touchdown), one sack, and one forced fumble in 14 contests. The season-ending injury resulted in a less imposing unit that was ultimately embarrassed in the NFC championship game by the Panthers, which his representatives are likely pointing to during the ongoing conversation about a contract extension. No matter if the sides come to an agreement, Arizona could be without its starting slot corner to start the upcoming campaign, if he deems himself unready.
