C Hjalte Froholdt will miss his first game since joining the Cardinals

Center Hjalte Froholdt will miss his first start since joining the Cardinals in 2023. Froholdt did not clear concussion protocol, ruling him out for Sunday's game against the Rams.Froholdt had started all possible 60 games since signing as a free agent.The Cardinals will also play without offensive lineman Jon Gaines II (ankle). That means Hayden Conner will start at center.Defensive lineman Zach Carter, who has had three limited practices since coming off injured reserve with a knee injury, is also out. The Cardinals list tight end Hunter Long (knee), defensive lineman Roy Lopez (toe/ankle), cornerback Max Melton (knee/hand), defensive lineman Darius Robinson (wrist), left tackle Jayden Williams (knee) and safety Dewey Wingard (groin) as questionable.Lopez returned to practice on Friday, as did Robinson, who was a DNP on Thursday. Robinson had a wrap on his wrist. Long would have to be activated to the 53-player roster by Saturday afternoon if he is to return this week.
