In order for Cardinals quarterback Carson Palmer to play Thursday, he has to pass the league's concussion test. And the wife test.
Arizona coach Bruce Arians said he's spoken with Palmer's wife, Shaelyn, about his condition because wives and loved ones tend to give a more accurate health reading than a coach can get from a player.
"Well, you're not going to get the real truth from a football player," Arians said on a conference call Tuesday. "He's always going to tell you he's ready and he's OK. I was counting on her to tell me what it was really like."
Palmer suffered his concussion in the fourth quarter of the Cardinals loss to the Rams after a tackle by Rams defensive lineman Aaron Donald.
Never miss a local story.
After consulting with Palmer's wife and meeting with Palmer Tuesday morning, Arians said there's "a chance" that Palmer could play against the 49ers. That decision will be made Wednesday.
"Just left a meeting with him and he looked good, so we'll wait and see," Arians said. "He's got to go through the (concussion) protocol."
If Palmer can't play, Drew Stanton would get his first start of 2016 and his first since the 2014 season. Stanton faced the 49ers early that season, a 23-14 Cardinals win in Arizona in which Stanton had 244 passing yards and two touchdowns. Stanton completed four of11 passes for 37 yards Sunday with two interceptions against the division-leading Rams.
"He's done it," Arians said of Stanton. "He was 5-3 as our starter when Carson was hurt (in 2014) and I thought he played extremely well. We won't change anything we do. He's extremely knowledgeable in the offense and I feel very comfortable with him in there."
