Sewell is trying to challenge Jack Sanborn for the Bears' starting job at middle linebacker, Adam Jahns of The Athletic reports.
Although Sanborn is currently the starter, he missed a couple tackles in the Bears' first preseason game, while Sewell, the team's fifth-round pick, has had an impressive camp. There is a chance the depth chart changes at some point, though nothing seems imminent. Whichever player starts at middle linebacker, he is potentially a strong IDP option.
