The San Francisco 49ers are set to lose a key member of their coaching staff to a division rival, as the Seattle Seahawks announce the hiring of Brian Fleury, the 49ers' tight ends coach, as their new offensive coordinator. This move was confirmed in multiple reports as of February 2026 and represents both a significant professional step for Fleury and a strategic gain for the Seahawks, led by their head coach Mike Macdonald.
Brian Fleury's tenure with the 49ers has been marked by a fast rise through the coaching ranks since joining the team in 2020. Initially hired as an offensive assistant, Fleury quickly became indispensable to San Francisco's complex and dynamic offensive scheme. His promotion to tight ends coach in 2022 placed him in direct charge of one of the NFL's most versatile and productive tight end groups, highlighted by George Kittle, alongside emerging talents like Brayden Willis. Fleury's role was critical in maintaining and evolving the offensive system that has consistently ranked among the league's best in efficiency and scoring.
The Seahawks' decision to hire Fleury is a clear indication of their aspirations to revamp and upgrade their offense. Under Mike Macdonald, Seattle is in a rebuilding phase and aims to implement elements of the successful outside zone running, play-action, and pre-snap motion concepts that the 49ers have masterfully executed for years. Fleury's direct experience with the 49ers offense and his familiarity with NFC West defenses, including the 49ers' own, present Seattle with a tactical advantage. The Seahawks will look to Fleury to adapt these principles to maximize the talents of their quarterback Geno Smith and a receiving corps featuring stars DK Metcalf and Jaxon Smith-Njigba.
The departure of Brian Fleury leaves a challenging gap for head coach Kyle Shanahan's staff. Shanahan has a strong track record of promoting from within to maintain continuity and ensure a deep understanding of his offensive system. Candidates to succeed Fleury as tight ends coach include assistant tight ends coach James Casey or offensive assistants Asauni Rufus and Brian Griese, all familiar with the team's philosophy and players. With Fleury's integral role in coaching George Kittle, who is noted for his multi-faceted skill set as a receiver and blocker, the transition will require someone capable of maintaining the high standards set for the position.
Brian Fleury's journey from an offensive assistant to a sought-after offensive coordinator underscores the 49ers' capabilities in developing coaching talent. His work has not only contributed to the success of one of the NFL's most potent offenses but also positioned him for this career advancement. Over the years, the 49ers coaching staff has been a fertile ground for future head coaches and coordinators, with names like Mike McDaniel, Robert Saleh, and DeMeco Ryans rising through the ranks. However, the trade-off for such success is continued annual turnover and the need to rebuild parts of the staff.
Being poached by a division rival intensifies the impact of Fleury's move. Twice a season, Fleury's deep knowledge of the 49ers' playbook and tendencies will present unique challenges for San Francisco. This shared knowledge could influence game planning and adjustments, adding an intriguing narrative layer to the already heated 49ers-Seahawks rivalry.
For the Seattle Seahawks, Brian Fleury's hiring is a declaration of intent, signaling their commitment to reinvigorating an offense that aims to compete at the highest level in the NFC West and the league overall. For Fleury, it represents a deserved opportunity to shape and lead an NFL offense with full responsibility. For the 49ers, it is a bittersweet acknowledgment of their status as a premier destination for coaching talent, even as they must now quickly replace a key architect of their offensive success.
As the NFL coaching carousel continues to revolve, the 49ers face the ongoing challenge of sustaining their championship-caliber team not just on the field, but also in the strategic recruitment and development of coaching personnel. Brian Fleury's move to Seattle exemplifies the delicate balance between developing excellence internally and confronting the consequences when that talent is sought after league-wide -- especially by a rival.
In conclusion, Brian Fleury's transition from the San Francisco 49ers to the Seattle Seahawks as offensive coordinator represents a major coaching shift in the NFC West for 2026. It highlights the continued influence of the 49ers coaching tree and the high value placed on the offensive knowledge developed under Kyle Shanahan's leadership. The 49ers will now look inward to find a successor capable of continuing the deep-rooted excellence Fleury helped establish.
