Warner listed as starter
ESPN NFL Insider Adam Schefter first reported Warner would play.
The team made no official announcement but Warner practiced all week and said his post-concussion symptoms had faded.
Warner had practiced all the previous week, but sat out last Sunday's 20-17 loss at Tennessee because of lingering symptoms from the concussion he sustained Nov. 22 at St. Louis.
The 38-year-old quarterback had started 41 consecutive games before missing the Titans game.
"He's experienced no symptoms, and he's feeling much better," Warner's agent, Mark Bartelstein, told NFL.com. "The Cardinals are taking every precaution, but I'd be very surprised if he didn't play."
Information from The Associated Press was used in this report.
