Cardinals head coach Jonathan Gannon announced that running back Trey Benson is being placed on injured reserve, via NFL Network’s Ian Rapoport.
Benson suffered a knee injury late in Arizona’s Week 4 matchup against the Seahawks last Thursday, but it was not originally thought to be serious, per ESPN’s Adam Schefter. That assessment changed very quickly; Benson has already undergone arthroscopic surgery on his meniscus and is expected to miss four to six weeks, according to Schefter.
Benson’s injury is another hit to a Cardinals backfield that already lost James Conner for the season. 2023 UDFA Emari Demercado will likely take over starting duties with Zonovan Knight and Michael Carter rotating in. Arizona also has D’Ernest Johnson on their practice squad.
Demercado has two starts in his career but has never been a lead back for multiple games. Knight has been a healthy scratch in two games with zero touches in the other two. Carter has been in the the NFL the longest, but his production has dipped significant since the start of his career.
The Cardinals have a Week 8 bye, so Benson’s four-game minimum IR stay would not elapse until Week 10, which fits with his projected recovery timeline. He may have a chance at returning to practice as soon as he’s eligible, though Arizona will likely give him time to ramp up after surgery.
In the meantime, the Cardinals were already struggling to move the ball on offense before their top two RBs went down. Now, quarterback Kyler Murray will be asked to do even more, though his performance to open the season has been underwhelming.
