The euphoria of DeAndre Hopkins' miracle catch to beat the Bills Sunday overshadowed what could be a crucial loss on the defense when veteran defensive lineman Corey Peters was carted off with a knee injury.
Coach Kliff Kingsbury still didn't have an official update to the severity on Monday, but "it didn't look good last night with Corey and it hasn't sounded good from what I've gathered (today)."
That would hurt on the field. It would also be a major blow to the locker room.
"Corey is a great leader," linebacker Markus Golden said. "He's a guy that took me under his wing. I've got a lot of respect for Corey. When you lose a guy like Corey – and I pray to God he'll be OK and we'll be able to get him out there – but when you don't have him, it's more than just football. He knows exactly how to calm us down when stuff is getting crazy.
"But I know Corey, he's going to want us to go out and play hard for him and do whatever we need to do to win."
The Cardinals could potentially have to juggle some things on Thursday night when it comes to the defensive line. Zach Allen, Rashard Lawrence and Leki Fotu are already on injured reserve and Jordan Phillips missed Sunday and played just 12 snaps two weeks ago because of a problem hamstring. Lawrence and Allen are eligible to return, although only Lawrence has returned to practice so far.
Their only healthy linemen now are Angelo Blackson, Josh Mauro and Trevon Coley, although Michael Dogbe is on the practice squad.
"There is definitely concern there," Kingsbury said. "It's a quick turnaround after a physical game. We'll see how that progresses."
Peters, who is scheduled to become a free agent after the season, has dealt with injuries before, and his first season in Arizona in 2015 was derailed when he had a season-ending Achilles injury in training camp.
Since then, Peters has missed only six games in four-and-a-half seasons and evolved into one of the Cardinals' main leaders.
"Man, Corey is like my big brother," tackle D.J. Humphries said. "He's been around for my whole journey, the ups and the downs. To see him go down like that, it was really unfortunate. One thing I know about Corey, he's resilient and a tough guy. He's always going to be in good spirits.
"All of his wisdom he's can pass on to the guys, he's going to pass on. He'll always be a part of us, whichever way it goes."
Neither the Cardinals or Seahawks practiced Monday but they were required to put out estimated injury reports, and both teams had lengthy lists.
For the Cardinals, listed as DNP were Peters, LB De'Vondre Campbell (calf), TE Darrell Daniels (ankle), G Justin Murray (hand), DL Jordan Phillips (hamstring), LB Haason Reddick (neck), S Jalen Thompson (shoulder), S Charles Washington (groin), TE Maxx Williams (ankle), WR Larry Fitzgerald (not-injury related) and Hopkins (not-injury related). Limited were S Budda Baker (groin), RB Kenyan Drake (ankle) and CB Dre Kirkpatrick (hamstring).
For the Seahawks, DNP were T Duane Brown (knee), RB Chris Carson (foot), CB Quinton Dunbar (knee), G Kyle Fuller (ankle), CB Shaquill Griffin (hamstring/concussion), WR Tyler Lockett (knee), C Ethan Pocic (concussion), DT Jarran Reed (hand) and CB Neiko Thorpe (core). Limited were RB Travis Homer (hand/thumb), RB Carlos Hyde (hamstring), DE Benson Mayowa (ankle), TE Greg Olsen (foot) and LB K.J. Wright (ankle).
PRACTICE SQUAD MOVES
The Cardinals signed a pair of linebackers to the practice squad Monday. Stephone Anthony is a one-time first-round pick of the Dolphins. Terrance Smith is cousins with Hopkins and has know defensive line coach Brentson Buckner his whole life.
