Wilks was in Arizona for a second interview last week.
Cardinals offensive tackle D.J. Humphries also expressed support for Wilks, who like him is a native of Charlotte.
The Cards named Wilks, the Panthers defensive coordinator, their new head coach on Monday after Arians retired earlier this month.
Prior to signing on with the Panthers, Wilks was the defensive backs coach for the Chicago Bears (2006-2008) and then the San Diego Chargers (2009-2011).
Wilks, who is available right now, is a top-end candidate, nearly reminiscent of the Bruce Arians hire for the Cardinals in 2013. Wilks, who served as the defensive coordinator for the Carolina Panthers last season, becomes the team's 10th head coach since the franchise moved to the desert in 1988.More news: Trump's trouble in the polls: Approval rating 'lowest on record'
Per Garafolo and CBS Sports' Jason La Canfora, the Cardinals no longer have any second interviews scheduled for the head coach vacancy.
Under Wilks' leadership this season, the Panthers were seventh in total defense, 11 in points allowed, third in rush defense and third in sacks.
Despite mediocre numbers from the Arizona defense in 2017, Wilks inherits quite a lot of talent on that side of the ball.
With a solid foundation and plenty of young talent, the Cardinals could become one of the best defensive teams in the National Football League under Wilks.
Cardinals cornerback Patrick Peterson was seemingly impressed by reports of Wilks' appointment, writing "I LOVE IT" on his Twitter page.
