San Francisco 49ers GM John Lynch provided a concerning update on defensive end Drake Jackson at the NFL Scouting Combine, highlighting the challenges associated with his quad tendon injury. Lynch noted parallels with former player Mike McGlinchey, who still deals with pain post-repair. Since being drafted in 2022, Jackson has struggled with injuries, limiting his impact on the field to just 23 games over two seasons. Lynch expressed hope that Jackson could turn his health around, emphasizing the team's reliance on a strong draft class to bolster their defense.
