The team confirmed that a process will be established "at the appropriate time" for the team's sale.
NFL Media Insider Ian Rapoport reported Thursday, per a source with in-depth knowledge of the situation, that March 2015 is a realistic benchmark for the team to be sold by Wilson's family to a new owner. The Bills will consult with the NFL soon on the issue.
In a statement, Mary Wilson said team president Russ Brandon will continue to guide the team's day-to-day operations with the ultimate goal: winning.
"I have complete confidence in Russ Brandon, our president and CEO, to continue his duties of running the organization. General manager Doug Whaley and head coach Doug Marrone remain empowered by Russ to run the football operation," Wilson said.
