The San Francisco 49ers are adjusting to a significant change in their linebacker corps after losing Dre Greenlaw to the Denver Broncos and De'Vondre Campbell, who remains unsigned. In response, the team has bolstered its lineup by acquiring veterans Luke Gifford and Chazz Surratt while also drafting promising linebacker Nick Martin from Oklahoma State. Martin showcased impressive skills during offseason practices, suggesting he could compete for a starting position alongside Fred Warner. However, a recent injury resulted in a broken bone during training, raising concerns about his readiness for the upcoming season and the depth of the 49ers' defense.
