As expected, Cardinals rookie Carson Beck will make his first start at quarterback on Sunday against the Rams after Gardner Minshew suffered an elbow injury that requires surgery last week.

Head coach Mike LaFleur told reporters in his Wednesday press conference that he’s “real excited for Carson” to have this opportunity.

“Just go out and operate — go operate this offense and go play each play as its own,” LaFleur said of his message to the young QB. “Do what he’s been doing in practice. It’s just an extension of the practice field. Obviously, it’s live bullets and go operate. Go play this game.”

Beck has not yet made a regular-season appearance. But he did have an impressive preseason debut in the Hall of Fame game back in August before being sidelined by a rib injury.

LaFleur said he feels like Beck is ready to play.

“You never really know until you get to the live bullets on Sunday,” LaFleur said. “But just the way he goes about his business, whether it’s been from OTAs through training camp before he got hurt, obviously, seeing him operate there in that first half plus the one possession in the second half [of the Hall of Fame game].

“So, obviously we’ll know more come Sunday, but have all the confidence he’s ready to roll.”
