Just Hours After Signing His Extension, 49ers’ Right Tackle Thanks the Front Office for Believing in Him and Giving Him the Chance to Stay in San Francisco

San Francisco, California — December 19, 2025 — As the San Francisco 49ers move into the most critical stretch of the season, questions about the future of the roster have continued to swirl, particularly along the offensive line as the team prepares for a demanding playoff push. Against that backdrop, the front office made a decision that once drew skepticism from the outside: extending right tackle Colton McKivitz. And just hours after the deal became official, McKivitz broke his silence with a heartfelt message of gratitude.

McKivitz has never been the flashiest name on the roster, nor a regular fixture in highlight reels. But within Kyle Shanahan’s system, his role has been quietly essential. Tasked with protecting the right side of the line, McKivitz has been responsible for keeping Brock Purdy clean in the pocket and helping anchor one of the league’s most complex run schemes. The 2025 season has marked the best football of his career, as he has allowed just three sacks all year and earned top-tier grades from Pro Football Focus — a remarkable leap for a player once labeled as merely “serviceable.”

When the 49ers chose to extend McKivitz during the season, the move was met with doubt from portions of the fan base. Many believed San Francisco could pursue an upgrade through the draft or free agency. Instead, general manager John Lynch and head coach Kyle Shanahan opted for continuity, betting on McKivitz’s steady development, deep understanding of the scheme, and year-over-year improvement.

That faith did not go unnoticed. Within hours of the announcement, McKivitz addressed the decision, expressing appreciation in a manner that reflected the understated mentality the coaching staff values so highly in offensive linemen.

“I’m extremely grateful to the front office and coaching staff for believing in me,” McKivitz said. “San Francisco gave me the opportunity to grow, to prove myself, and being able to stay here and continue to play for this team means a great deal to me.”

For the 49ers, securing McKivitz provides critical stability both now and in the years ahead. With legendary left tackle Trent Williams entering the later stages of his career, locking down the right side eases long-term concerns along the offensive front. Rather than needing to solve both tackle positions simultaneously, San Francisco can now focus its future planning more deliberately — a significant strategic advantage.

Beyond the on-field implications, the extension sends a clear message throughout the locker room. The 49ers are willing to reward players who do the quiet, demanding work, show patience in their development, and put the team first. That philosophy has been a cornerstone of the organization’s sustained success in recent seasons.

Ultimately, McKivitz’s extension is more than a contract announcement. It reflects how the 49ers operate — trusting the process, investing in late development, and valuing the players who form the foundation of a Super Bowl-caliber roster. For McKivitz, the opportunity to remain in San Francisco is not simply a reward, but validation of a journey built on perseverance and belief.
