TEMPE, Ariz. -- Less than 24 hours after leaving the field in Seattle in an ambulance, Arizona Cardinals left guard Mike Iupati was walking around the team’s locker room back in Arizona.

Coach Bruce Arians said Monday that Iupati was laughing and smiling Monday afternoon despite being “a little stiff.” During his Monday morning news conference, Arians said Iupati was “fine” and will be day-to-day while going through the NFL’s concussion protocol as a precautionary measure.

Arians said on Arizona Sports 98.7 FM that there’s a possibility Iupati could play next Sunday night against Cincinnati.

“There’s a real good chance he’ll play this week,” Arians said.

When deciding if a player who went through a traumatic moment as Iupati did Sunday night will play in the next game, Arians said he tends to be extra cautious.

“It’s up to the player,” Arians said. “Sometimes, it’s harder for the player to get over. He’s healthy but it’s hard to get over it.

“When he’s ready, he’ll tell us.”

Iupati went down with a neck injury after pulling on a run by Chris Johnson late in the second quarter. After being attended to immediately by doctors from both the Cardinals and Seahawks, paramedics braced Iupati on boards and then strapped him on to a stretcher. An ambulance took him to a local hospital, where X-rays, MRIs and CT scans were all negative, general manager Steve Keim said during his appearance on the same Phoenix-area radio station Monday.

After talking with Iupati, Keim said the 28-year-old was “pretty sore.”

Iupati flew back to Arizona on the team’s charter.

“It was a very scary moment and we’re very happy to see him in the locker room smiling,” Arians said.
