A Missouri standout with 13 sacks in his collegiate career — including 8.5 his final campaign — Robinson had been battling fellow teammates Bilal Nichols and Justin Jones for a starting job on the defensive line, and in mid-August head coach Jonathan Gannon said the rookie “1,000 percent” had a chance to earn one.

Such speculation now moves to the back burner as he recovers.

The setback is especially tough for an Arizona defense desperately requiring improvement after it finished the 2023 season allowing the second-most points and tallying the third-fewest sacks in the NFL.

Fans were treated to only a fleeting glimpse of Robinson in preseason action, as he logged just 10 snaps, with one tackle and a quarterback pressure.

Following some unfortunate luck, his next game action won’t come until he’s overcome his injury.
