SANTA CLARA >> Fred Warner is seven seasons into one of the best careers ever by a 49ers linebacker. By virtue of a reported three-year, $63 million contract extension, he has more time ahead to prove worthy of joining Patrick Willis and Dave Wilcox in the Pro Football Hall of Fame.

The extension includes over $56 million in guarantees, according to ESPN’s Adam Schefter, who first reported the news Monday.

The team has yet to announce the deal, which surpasses that of Baltimore’s Roquan Smith among top-paid linebackers.

Warner, 28, was entering the final two years of an extension (five years, $95 million) he signed in 2021, at $17.65 million base salaries in 2025 and ’26.

Warner’s extension comes in the wake of this offseason’s other priority signings, for quarterback Brock Purdy (five years, $265 million) and tight end George Kittle (four years, $76.4 million).

His primary goal is to accomplish something that eluded both Willis and Wilcox: win a Super Bowl, which linebacker Keena Turner did four times from 1980-90.

“Listen, I never need more motivation to get up and be the best version of myself or for our team,” Warner said in April. “Even though we’ve been close to hitting the top of the mountain top, we’ve never actually surpassed it, right? So teams have never looked at us as Super Bowl champs because we haven’t attained that yet. That carries heavily on myself as it does other guys who’ve been here.”

With 896 tackles, Warner is 55 shy of surpassing Willis for the most in 49ers history. Willis played only six games in what proved his eighth and final season, with foot issues prompting his retirement. Wilcox’s official tackle total is unknown from his 1964-74 tenure as a seven-time Pro Bowler.
