TEMPE, Ariz. -- Tyrann Mathieu may have returned Sunday from a shoulder injury but he's not completely back to full strength.
"Last week coming off the shoulder, I still felt hesitant in some situations, couldn't really get out of the blocks in some situations," he said. "That's some things I got to work on. I got to play better, as well. I haven't been making the plays that I'm accustomed to making."
Mathieu was limited in Wednesday's practice and there were no signs he'd miss Sunday's game against Washington.
Washington coach Jay Gruden expects Mathieu to be on the field.
"I don't know much about his injuries. I know he's missed some time because of some injuries, but he looks good to me," Gruden said on a conference call. "He's always around the ball. You have to know where he is at all times. He's a good blitzer. He can cover tight ends. He's a great zone player, plays with his eyes and forces turnovers. So, I expect him to have a big game. I know that this is a very important one for them, as it is for us, and history says that if it's a big game, Tyrann shows up."
Cardinals cornerback Patrick Peterson missed Wednesday's practice with a knee injury he suffered Sunday against the Falcons, but coach Bruce Arians expects him to return to the field Thursday. Arians also said Tuesday on SiriusXM NFL Radio that he thinks Peterson would play this Sunday against Washington.
Cornerback Justin Bethel missed practice with a foot/knee injury, wide receiver John Brown was out with as a result of a sickle-cell trait episode and tight end Jermaine Gresham is suffering from an illness.
