Two projected starters for the Lions exit with potential injuries during first joint practice

East Rutherford — The Detroit Lions saw two key offseason additions exit practice to be evaluated for potential injuries during joint work with the New York Giants on Monday.

Right guard Kevin Zeitler left the field in the early stages of practice to get a shoulder issue looked at, while rookie cornerback Terrion Arnold exited for a concussion evaluation during a red zone sequence closer to the end of the day.

Zeitler was replaced in the lineup by Michael Niese, who spent much of last season on Detroit’s practice squad. The top guard off the bench for the team in 2023, Kayode Awosika, was returning from a two-practice absence and worked with the second-team offense on Monday.

Arnold got knocked from the action after absorbing a massive block from New York’s starting left tackle Andrew Thomas, who was pulling into the second level on a toss play to running back Devin Singletary.

Arnold has been working with the first-team defense most of training camp, opposite Carlton Davis III.
