The Cardinals lost cornerback Patrick Peterson to a concussion last Sunday, but his recovery is going well.

Coach Bruce Arians said Wednesday, via Darren Urban of the team’s website, that Peterson has passed the necessary steps to receive clearance to practice. He’ll still need to get a separate green light in order to play against the Cowboys in Week Nine, something that should come as long as Peterson doesn’t start feeling symptoms of the concussion again after his return to the field.

Peterson has had an up-and-down season and was having a rough time against Jeremy Maclin before he was knocked out of the game, although neither of those things is likely to make the Cardinals feel any better about heading into a game without him in the lineup.

Arians also said that safety Tony Jefferson is expected to take a test to progress to the next stage of the concussion protocol on Thursday.
