21 Patrick Peterson DB

Peterson (ankle) was a full participant at Thursday's practice, Darren Urban of the Cardinals' official site reports.

Peterson did not participate at Wednesday's practice, but it appears the team was understandably illustrating some caution with their star cornerback. The 27-year-old is expected to be available for Week 17 in Seattle and extend his consecutive starts streak to 112 games.

Peterson (ankle) didn't practice Wednesday, Josh Weinfuss of ESPN.com reports.

During Sunday's win versus the Giants, Peterson only played 79 percent of the snaps on defense. Most of the missed time was devoted to a concussion test, Peterson relayed to Weinfuss after the game, but he hasn't entered the protocol for head injuries in the interim. Fast forward to the first practice of Week 17 prep, and Peterson is now dealing with an ankle concern, which head coach Bruce Arians termed "not very" severe, per Weinfuss. Adding to the positive tone is Arians' hope that Peterson makes an appearance in Thursday's session, a belief that bodes well for the cornerback extending his consecutive starts streak to 112 games Sunday at Seattle.

Peterson said he was evaluated for a concussion during Sunday's game against the Giants but avoided the league's concussion protocol, ESPN NFL Nation's Josh Weinfuss reports.

Peterson can generally be taken at his word on this, but his availability for Week 17 perhaps shouldn't be taken for granted at the moment -- that he was evaluated for a concussion might make his symptoms worth monitoring in the upcoming days. For now, though, the belief is that he suffered no injury.

Peterson (hamstring) is active for Sunday's game against the Titans, Darren Urban of the Cardinals' official site reports.

The Cardinals will be happy to have their top corner back Sunday, but fantasy owners should see Peterson as a risky option. Titans QB Marcus Mariota is averaging just 27 pass attempts over the last three games, which could keep the ball away from Peterson.

Peterson (hamstring) was a limited participant at Friday's practice and is considered questionable for Sunday's matchup against the Titans, Josh Weinfuss of ESPN.com reports.

Peterson's hamstring injury kept him sidelined during Thursday's practice, but he's currently trending in the right direction with high hopes of playing in Week 14. The Cardinals' No. 1 cornerback said his hamstring is still a "little sore" but will be ready to play Sunday, according to Darren Urban of the team's official site. At this point all signs point to Peterson suiting up without limitations, though Brandon Williams could be in line for additional snaps if Peterson were to suffer any sort of setback.
