Tell recorded a pair of solo tackles before hurting his groin in Sunday's 21-18 preseason win over the Panthers.
Tell opted out of the entirety of last season, and now the 2019 firth-rounder will have to gut through an injury as he attempts to make the regular-season roster. In 13 games as a rookie two years ago, he totaled 26 tackles, five pass defenses and one forced fumble.
