ALLEN PARK -- The frustration in Cardinals coach Kliff Kingsbury’s voice could be felt from across the country when asked about what Detroit’s newest practice squad quarterback knows about his offense.

“Pretty much everything," Kingsbury said sarcastically during a conference call with reporters. "What he says is exactly what we’re going to run in the game. So, yeah, that’s tough for us.”

The Lions signed Chad Kanoff and wide receiver Marvin Hall to their practice squad on Wednesday. Detroit released running back Mark Thompson and receiver Jonathan Duhart in its corresponding move to make room.

Kanoff was included on the Cardinals first wave of cuts after completing 10 of 19 passes for 128 yards with one touchdown and one interception in three preseason games. The Princeton graduate signed with the Cardinals as an undrafted free agent after the 2018 draft. He spent some time spread across two seasons on their practice squad.

Despite the evident frustration, Kingsbury said the Cardinals are facing just as much mystery in Detroit’s defense as the Lions are with the debut of his offense in the NFL.

“I think that’s been overplayed, you know there’s 10 years of play calling and body of work you can draw from,” Kingsbury said of all the talk surrounding the mystery of his NFL regular-season debut. "Regardless of the level, there’s plenty of film out there that just like I really don’t know what they’re going to run defensively based upon last year’s film.

“They’ve had all summer to tweak and change, and we’ve had the same. I think that’s been overblown a little bit, but that’s all part of the gamesmanship.”

The Lions and Cardinals kick off the regular season Sunday with a 4:25 p.m. game at State Farm Stadium in Glendale. This matchup represents the NFL debut of first-overall pick Kyler Murray and Kingsbury. Detroit is also set to reveal its new-look offense under coordinator Darrell Bevell.

As for what Kingsbury wants to see out of his rookie quarterback Sunday, he said “I just want him to play his game, cut it loose.”

“We know there’s going to be some ups and downs, it’s not easy starting Day One as a rookie quarterback in this league and we understand that,” Kingsbury said. "I want him to just relax, know he doesn’t have to win or lose a game by himself and go out there and do the best that he can.

“One of the best fronts in football, one of the best corners in (Darius) Slay. They can put him on anybody and really take them out of the game. I think Matt (Patricia) does a tremendous job, so does coach (Paul) Pasqualoni, of really adjusting to your offense and taking away what you do best and taking away your best players. It will be a huge challenge for us."
