Mary Wilson, the widow of former Buffalo Bills owner Ralph Wilson, is now the controlling owner of the team, the Bills announced Thursday.
The Bills confirmed that the franchise will eventually be sold, saying that "a process will be established at an appropriate time" for the sale.
"This process will ensure that the club complies and is faithful to NFL rules and to its obligations to New York State and Erie County," the team said in a statement.
Ralph Wilson died last week at the age of 95. Mary Wilson, whom he married in 1999, was his third wife.
Bills CEO Russ Brandon will retain operational control of the team.
