GLENDALE, Ariz. -- The Arizona Cardinals released defensive end Robert Nkemdiche on Saturday, one day after he arrived at training camp out of shape.

Coach Kliff Kingsbury didn't hold back when asked Friday about how the former first-round pick showed up to camp.

"Not in shape, I guess," the usually reserved Kingsbury said. "And that's kind of where we'll leave it. I mean, he's on [the physically unable to perform list], and he's working through that. When he is cleared, we'll work with him."

Not In A Zona Since drafting Patrick Peterson in 2011, the Cardinals have struggled to convert on their first-round picks. Only three of their eight from that span are still on the team. Here's a look: Drafted Current K. Murray 2019 ARI J. Rosen 2018 MIA H. Reddick 2017 ARI R. Nkemdiche 2016 Cut Sat. D.J. Humphries 2015 ARI* D. Bucannon 2014 TB J. Cooper 2013 OAK M. Floyd 2012 BAL * Has played 27 games in three seasons

Kingsbury's answer was a detour from his typical responses this offseason. The first-year coach has developed a reputation for saying little about players and not naming names.

""It's just a performance-based business and we decided as an organization that was best for us," Kingsbury added on Sunday. "We wish him well and hope he gets a fresh start somewhere else. And that's really all it came down to."

Nkemdiche, 24, the 29th overall pick in the 2016 NFL draft, was arrested June 6 for speeding and driving with a suspended license.

A defensive lineman whose career has been riddled with injuries -- he had been recovering from ACL surgery in December -- the Ole Miss product has 44 career tackles and 4.5 sacks, the latter all coming in 2018. The Cardinals did not pick up the fifth-year option on his contract.

"I'll internally bleed red forever, thankful for the opportunity to grow as a player and experience the culture it was an ecstatic ride," Nkemdiche wrote in an Instagram post. "The fans, coaches, teammates only love and genuine moments. But, Nothing last forever time to continue the journey and keep elevating,on to the next fix ... let's go!!!!!!!!!!"
