Kurt Warner went through another full practice on Friday, but the Arizona quarterback was listed as questionable for Sunday's game at Tennessee.
Warner practiced all week after sustaining a concussion in last Sunday's 21-13 victory at St. Louis. He passed all the required mental tests on Tuesday.
Warner and Cardinals coach Ken Whisenhunt have said they plan to be cautious as they deal with the head injury. Warner said he didn't want to give anyone a "false sense" he was OK, but he obviously is optimistic.
In addition to the concussion, Warner has had tightness in his neck but said it loosened up Friday morning and that he felt more comfortable than all week.
Warner has started 41 consecutive games for Arizona. If he doesn't go, Matt Leinart is the backup.
Also listed as questionable is kicker Neil Rackers with a sore groin.
