George Kittle Opens Up About Retirement Timeline Amid Injury Battles and Age Concerns — Vows to Play His Final Game in a 49ers Uniform

SANTA CLARA, California — The San Francisco 49ers are accelerating their efforts to upgrade the offensive line, and one veteran name has emerged as a primary target: Joel Bitonio, the seven-time Pro Bowler from the Cleveland Browns. According to multiple league sources, the 49ers are among the most aggressive teams pursuing Bitonio as free agency approaches. With an elite pass block win rate and extensive experience at left guard, Bitonio is widely viewed as an ideal stabilizing presence for Kyle Shanahan’s offensive system. From a football standpoint, the fit makes sense. San Francisco currently faces uncertainty at left guard, lacking proven depth and consistency at the position. Pairing a savvy, technically sound veteran like Bitonio alongside All-Pro left tackle Trent Williams would significantly reinforce the left side of the line — a critical area in Shanahan’s play-action-heavy offense and in longer-developing pass concepts. But this is where the complication begins. Trent Williams’ contract has become a central offseason storyline. The veteran tackle is scheduled to carry a cap hit approaching $40 million in 2026, and the 49ers front office is actively working to restructure or adjust his deal. Until that situation is resolved, committing major financial resources elsewhere along the interior line carries substantial risk. If Williams remains in place under a reworked and cap-friendly structure, signing Bitonio becomes a clear win-now move. However, if negotiations stall or introduce uncertainty, investing in a 34-year-old guard next to a 37-year-old tackle could become a durability gamble at a crucial position. The 49ers understand their championship window remains open. But balancing short-term competitiveness with long-term financial flexibility is delicate — especially when aging veterans are involved. For now, the Joel Bitonio pursuit appears real and advancing. Yet its completion depends almost entirely on how quickly and smoothly the Trent Williams contract situation is resolved. In the coming weeks, the timing of that agreement may ultimately determine whether San Francisco finalizes one of the most intriguing offensive line upgrades of the offseason.
