49ers Lock Down Colton McKivitz with a $45M Extension

San Francisco, CA — September 8, 2025

The San Francisco 49ers have ensured stability in the trenches for years to come, inking guard Colton McKivitz to a three-year, $45 million extension that includes $27 million guaranteed. The deal, finalized Monday, comes as McKivitz was entering the final season of his previous contract and solidifies his role as one of the cornerstones of the offensive line.

A Vital Piece of the 49ers’ Success

McKivitz, a 2020 fifth-round pick out of West Virginia, has steadily developed into one of the NFL’s more reliable interior linemen. Known for his versatility, he has played both tackle and guard during his career but has settled into a starting guard role, providing consistency and toughness in pass protection and the run game.

His growth has mirrored the 49ers’ offensive resurgence. With Christian McCaffrey thriving as a dual-threat weapon and Brock Purdy emerging as the team’s quarterback of the future, McKivitz’s ability to control the line of scrimmage has been instrumental in keeping the offense balanced.

“Colton embodies what we’re about—hard work, resilience, and team-first football,” general manager John Lynch said in a statement. “This extension rewards his contributions and ensures we maintain continuity up front.”

Continuity Along the Line

For San Francisco, retaining McKivitz was about more than rewarding one player—it was about securing the foundation of their offense. Alongside stars like Trent Williams, the 49ers have prioritized maintaining one of the league’s most cohesive offensive lines.

The extension also signals the team’s commitment to protecting Purdy and preserving a run-first identity under head coach Kyle Shanahan. In a league where offensive line depth can be difficult to find, locking down a proven starter provides reassurance for the franchise and its fanbase.

Player Reaction

McKivitz, never one for headlines, expressed gratitude after signing the deal.

“It means a lot to me and my family,” he said. “The 49ers believed in me when I came into this league, and I’m proud to continue building with this team. The goal is a championship, and this is just the start.”

His humility and work ethic have made him a respected figure in the locker room, often described as one of the team’s unsung heroes.

At $15 million per year, McKivitz’s deal places him among the higher-paid guards in the NFL, reflecting both his current performance and projected importance in the years ahead. The guaranteed money ensures security while allowing the 49ers flexibility to continue building around their core.

NFL analysts praised the move as both prudent and forward-thinking, highlighting how offensive line stability often makes the difference between good teams and true contenders.

The 49ers enter the 2025 season with championship aspirations once again, boasting one of the league’s most talented rosters on both sides of the ball. By ensuring that McKivitz remains part of their long-term plans, San Francisco has taken another step toward sustaining success in a highly competitive NFC landscape.

With his future secured, McKivitz can now focus fully on anchoring the offensive line as the 49ers chase another deep playoff run.

The 49ers’ decision to extend Colton McKivitz underscores their philosophy: build from the trenches out. By keeping one of their most dependable linemen in-house, San Francisco not only rewards consistency but also safeguards the foundation of their offensive identity.

For a franchise aiming for Super Bowl glory, this is a win both on and off the field.
