Peterson missed practice with an illness he caught Wednesday morning, Arians said.
“We’ve had about four or five guys that have had it now,” Arians said.
Wide receiver Michael Floyd was sick during Sunday’s game. He was up most of Saturday night fighting an illness, general manager Steve Keim said earlier this week.
Wide receiver Brittan Golden (groin) and linebacker Kevin Minter (knee) worked on a side field during the open portion of practice. Minter was wearing a knee brace. Starting left guard Mike Iupati (ankle) and defensive tackle Ed Stinson (hip) also didn’t practice.
Starting right guard Earl Watford (shoulder) was among seven Cardinals who were limited, joining cornerback Justin Bethel (foot), safety Christian Bryant (groin), safety Deone Bucannon (ankle), safety Tyrann Mathieu (shoulder), defensive tackle Corey Peters (foot) and cornerback Tharold Simon (ankle).
Nose tackle Xavier Williams (ankle) was listed on the injury report but practiced in full.
