Arizona Cardinals rookie quarterback Josh Rosen suffered a foot injury during Thursday's 45-10 loss to the Denver Broncos.

According to ESPN.com, Arizona head coach Steve Wilks said the rookie is being further evaluated and "probably" shouldn't have still been in the game when he suffered the injury in the fourth quarter.

"He thinks he's fine, but I'm not going to sit here and say that that may be the case," Wilks said.

The 21-year-old was selected by the Cardinals with the No. 10 overall pick in this year's draft with the expectation he would develop into a franchise quarterback following the retirement of Carson Palmer. That ushered in a new era of Cardinals football, as Wilks was also hired this offseason to take over as head coach.

In his college career, Rosen threw for 9,340 yards, 59 touchdowns and 26 interceptions, completing 60.9 percent of his passes. He earned a reputation for having one of the smoothest throwing motions and most mechanically sound games among quarterbacks in the 2018 draft along with an outspoken personality off the field. 

Rosen wasn't expected to start immediately in Arizona, with veteran Sam Bradford locked in place. But he was already impressing Wilks and the coaching staff early in the offseason.

"This guy is extremely smart," Wilks said in May, per Darren Urban of AZCardinals.com. "I mean, his ability to see certain things from the defense, and pick it up quickly, and execute... I don't want to say this, but he has the mindset of a vet. The way he sees the game.

"He's not playing like a vet. Make sure you guys understand that," he added. "He's still a rookie, OK? But he sees things, like I said before, through a different lens. And he picks it up quickly."

Ultimately, Rosen took over the starting job from Bradford, but the Cardinals may have to turn toward the veteran or Mike Glennon if the UCLA product is sidelined following this setback.
