SANTA CLARA, Calif. — The San Francisco 49ers didn’t flinch when they lost starting guard Spencer Burford to the Las Vegas Raiders. The front office dialed up an immediate response. The Robert Jones 49ers addition brings a 322-pound enforcer to the Bay Area, answering major questions about how San Francisco plans to keep Brock Purdy upright during the 2026 season.
Burford secured his payday, taking a one-year, $3.25 million deal with the Raiders. He leaves behind massive cleats to fill after helping drive the 49ers to the Super Bowl in 2024. San Francisco refused to wait around. NFL Network’s Tom Pelissero confirmed the team quickly agreed to terms with Jones, injecting fresh muscle into the interior line.
Jones brings serious trench experience. The 27-year-old logged 49 games and 30 starts during a four-year run with the Miami Dolphins. He signed with the Dallas Cowboys last spring but missed the entire 2025 season after suffering a broken bone in his neck during training camp. Now fully cleared, the former undrafted free agent heads to California with a massive chip on his shoulder. You can almost hear the pads popping already as he looks to prove he still dominates at the NFL level.
Jones already speaks the language of Kyle Shanahan’s offense. He played under Mike McDaniel in Miami. McDaniel, who learned the ropes as Shanahan’s deputy in San Francisco before eventually taking the Los Angeles Chargers offensive coordinator job in January 2026, runs a nearly identical scheme. The blocking concepts overlap heavily. Jones knows exactly how to execute the wide-zone runs this playbook demands, meaning he skips the steep learning curve most new linemen face.
“He missed last season because of a neck injury. He’s healthy now and headed to San Francisco.”

Jones slides right into a high-stakes environment. He links up with rising guard Dominick Puni to blast open rushing lanes for Christian McCaffrey. The 49ers operate in strict win-now mode. After aggressively locking down future Hall of Fame wideout Mike Evans in free agency and deploying explosive weapons like Ricky Pearsall, the offense needs a brick wall up front.
The NFC West punishes weak offensive lines. The division remains an absolute meat grinder. By adding a healthy, motivated Jones, San Francisco ensures their heavy-hitting offense doesn’t skip a beat. If he shakes off the rust quickly, he transforms from an injury-reclamation project into a crucial piece of a Super Bowl puzzle.
