One hour into his first stint with the Arizona Cardinals’ first team defense, cornerback Ronald Zamort’s season went up in flames.

A rising star, Zamort got his promotion on Saturday after Justin Bethel suffered a hyper-extended knee. Per Kent Somers of azcentral sports, the second-year player out of Western Michigan had been making quite the impression through the first week of training camp.

“But the feel-good story ended about one hour into Saturday’s Red and White practice. Zamort crumpled in the end zone because of an injury to his right knee. Tests confirmed that Zamort suffered a torn ACL and is out for the season.”

This is not only a devastating injury for Zamort, but it’s a big one for the Cardinals as a whole.

Already a question mark heading into the season, the team’s cornerback situation is a precarious one. Somers reports there are just five healthy corners on the roster at this time, which is extremely low. Not surprisingly, head coach Bruce Arians told reporters the team would likely be adding a cornerback via free agency.

After the Cardinals lost so much talent in free agency this offsesaon, it’s looking like they’ll be in a tight spot on this side of the ball heading into the 2017 season. It’s not the most positive development for this team, which is coming off one of its most disappointing campaign in years.
