49ers defensive staff outlines special role for rookie linebacker Jaden Dugger

During Thursday's practice, the San Francisco 49ers gave rookie linebacker Jaden Dugger a look with the first-team defense, prompting defensive coordinator Morris to elaborate on a new hybrid linebacker concept. When asked about a "fever" linebacker mentioned by veteran Dre Greenlaw, Morris explained that the role blends traditional backer traits with the ability to shift between coverage, edge rush, and nickel-style duties.

Dugger, a fifth-round selection who transitioned from safety to off-ball linebacker, possesses the physical profile of a defensive end, standing 6-foot-4 and weighing 240 pounds with long arms. His background and athleticism enable him to line up in coverage or press against the line of scrimmage, fitting the flexible scheme Morris described. The 49ers are experimenting with such versatile players to counter modern offenses that manipulate personnel groups. While Dugger still has a developmental path ahead, his early involvement signals the team’s interest in molding him into this multi-role position.
