I couldn’t find any credible reports that legendary coach Don Granato has returned to the Buffalo Sabres as a senior coach at KeyBank Center. The most recent confirmed coaching news is that he was fired as head coach on April 16, 2024, ending a 122–125–27 tenure and the team’s 13-season playoff drought
Since then, there have been no announcements—official or leaked—about Granato rejoining the organization in any capacity. Typically, such a move would garner significant media attention given his popularity among fans and his developmental track record, but I found none .
If this report is accurate, it’s extremely fresh and might not yet be reflected in mainstream sources. If you have a link or source for this breaking story, I can look further. Otherwise, based on current information, no such return has occurred.
