Jeffrey Gundlach, a high-profile bond-fund manager, has expressed interest in buying the Bills, according to the Wall Street Journal.
Gundlach told the paper that he has floated the idea of forming an ownership group to some of his wealthier clients, although the talks are still in the early stages.
Upon hearing Gundlach's comments, the Bills responded with an email to the paper.
"(Owner Ralph) Wilson has commented publicly many times that he has no intention of selling the team. Beyond that, our team does not offer a comment to this topic."
Former Buffalo Sabres owner Thomas Golisano and California real estate executive Ed Roski have previously expressed interest in purchasing the team.
