News: Jefferson (concussion) is eligible to play in Sunday's game against the Cowboys, after clearing the final step of the NFL's concussion protocol Thursday, Kent Somers of the Arizona Republic reports.
Impact: Jefferson is seemingly now on track to play, but he was limited at Thursday's practice, after which he said that he didn't remember parts of Sunday's win over the Eagles, ESPN.com reports. He also said that he doesn't want to rush back from a concussion, as one might expect. Jefferson has an impressive 50 tackles (45 solo) through seven games, but with four Cardinals' safeties getting significant playing time, his snaps and tackles had both tailed off in recent weeks, until Sunday's 12-tackle effort against the Eagles.
News: Peterson (concussion) practiced in full Thursday, FOX Sports 910 Phoenix reports.
Impact: After emerging from the concussion protocol Wednesday, Peterson fit in a limited showing in drills, and his upgrade to full practice all but assures his presence in the Cardinals' defensive backfield Sunday at Dallas. Expect Friday's injury report to confirm his Week 9 availability.
News: Jefferson (concussion) was limited in Thursday's practice but must complete another step in order to emerge from the league's concussion protocol, Kent Somers of the Arizona Republic reports.
Impact: Typically, tests must be conducted 48 hours apart, so Jefferson may enter the weekend with questionable status, if he remains embedded in the protocol. An absence would result in Deone Bucannon taking over at strong safety, but consider the situation fluid for the time being.
