Lions rookie CB Terrion Arnold evaluated for concussion

Detroit Lions rookie cornerback Terrion Arnold was evaluated for a concussion after exiting Monday's fight-filled joint practice with the New York Giants, the team announced.

The first-round draft pick from Alabama exited the morning session in East Rutherford, N.J., shortly after absorbing a massive block by Giants left tackle Andrew Thomas.

Arnold, 21, was selected 24th overall in April's draft after registering five interceptions and 63 tackles in 14 games for the Crimson Tide as an All-American in 2023.

Lions guard Kevin Zeitler also departed with a shoulder injury, while tight end Sam LaPorta (toe) did not participate.
