Warner became one of three players in the NFL to register 130-or-more tackles in each of the previous four seasons (2021-24) and became the second linebacker in franchise history to register 10.0-or-more sacks and 10-ormore interceptions in a career (LB Keena Turner).
The 2023 San Francisco 49ers defense finished in the top10 in the NFL in total defense (303.9) and rushing defense (89.7), tied for first in interceptions (22) and tied for the seventh-most sacks (48). Webster worked with Warner, who earned Associated Press First-Team All-Pro honors and was selected to the Pro Bowl Games after leading the linebacker unit with a team-high 132 tackles, 11 passes defensed, four interceptions, four forced fumbles and 2.5 sacks. LB Dre Greenlaw added 120 tackles, 1.5 sacks and four passes defensed.
